The technical field

The present invention relates to a method of recording and/or reproduction for the recording medium, playback device, recording medium, a method of determining the carrier, the method of recording and/or reproducing device using a recording medium that can be used as the recording media data on which is recorded the address information representing the position of the zero track, etc.

Prior art

In recent years there have been developed optical disks, which are used as the recording media with a large capacity. For example, the famous CD (compact disk) for musical information, CD-ROM for computer data and DVD (digital versatile disc or digital video disc) video information. These disks are disks, read-only. Recently received the commercial use of such optical discs, such as CD-R (CD recordable) and CD-RW (CD rewritable), which allow you to record and overwrite the data.

On the above recording media in the form of a disc, such as CD, CD-ROM, CD-R and CD-RW on the inner side region of the program in which the recorded data, formed the control data, which is called the zero track. In addition, on the outer side areas of the program form is : another area which is called the end zone. In these areas is address information and time information recorded on the disk.

Prior consistent format address information is, for example, on CD-R or CD-RW using the "lobularia" guide groove for the laser beam (hereinafter referred to as groove). While using lobularia track consistently provides information about the location or time information. CD-R/CD-RW data is written to disk by using the link on the address information, which is obtained by decoding information lobularia track. CD-R/CD-RW disc, the address information is obtained so that the information of lobularia stands out from the signal read from the disc in the form of a frequency-modulated signal with a carrier frequency of 22.05 kHz, and then demodulates the selected information lobularia. The address information referred to as ATIP (Absolute time in pre-formed track). Absolute addresses on the disk is represented by the absolute time information.

Absolute address consists of the information of time, in minutes, seconds and frames (MSF format). In MSF format decimal digit minutes, seconds and frames is represented by the BCD (BCD encoding). One second = 75 frames. Can the be presented addresses from 00 minutes 00 seconds 00 frames up to 99 minutes, 59 seconds, 74 of the frame. One digit in the decimal encoding is represented by four bits in the binary-decimal encoding. For ATIP requires 24 bits.

On CD-R or CD-RW drive control signals in addition to audio information is recorded using ATIP in the area of the zero track. The control signals include a start address of the zero track (referred to as the start time of the zero track) and the maximum starting address of the destination zone (referred to as start time end zone). The start time of the zero track and start time end zone represents the information that is read by the drive when a CD-R/CD-RW is loaded in the recording device and playback. This information is important for use of the loaded CD-R/CD-RW.

Using the code error detection (CRC) for each frame in the encoding ATIP can be detected by the error address information of the starting time of the zero track and start time end zone. However, it is impossible to ensure reliable detection of this error. To improve the reliability of the address information can be used encoding detection/error correction, which allows to obtain higher reliability. This increases the amount of redundant code, such as code inspections on h is tnost. As a result, the redundancy of the code leads to performance deterioration. As for the CD-R disc for which the disc format is already standardized, the encoding detection/correction of errors difficult to change.

In addition, depending on the use case, even if you use the standard recording media such as CD-R, you may want to use the recording medium with the lowest possible value of the eccentricity. However, in standard versions of the disks do not need to make the identification of such a disk. Thus, the method of determining the drive is missing.

Thus, the present invention is directed to a method of recording and/or reproducing on the recording medium, playback device, recording medium, method of determining the recording medium and method of recording and/or reproducing device using a recording medium, which enables you to record information about the error such as the start time of the zero track or start time end zone, which represents the position of the area, which should be determined by using the address information, and using this information, the address should be the determination of the disk.

The best ways to embodiments of the present invention

Next will be described one embodiment of the present invention. This variant of the embodiment shown in the application example of the present invention to CD-R. figure 1 shows an example of the recording device and disc (hereinafter referred to simply as the drive). In figure 1 the position 1 labeled optical disk with recording capability, for example, CD-R Optical disk 1 rotates at a constant linear velocity or constant angular velocity by using the engine brasenia disk. The optical sensor 3 is located so that it writes data on the optical disk 1, and reads data from the optical disk 1. The optical sensor 3 is moved along the radius of the disk 1 by an electric motor 4 to the drive.

As shown in figure 2, the optical disk 1 in accordance with one alternative embodiment of the present invention has a Central hole and a landing zone of the disk. The Central hole formed in the center of the optical disk 1. The landing zone of the disk is formed around the center hole. In the direction from the inner part to the outer part of the disk shaped region PCA (power calibration of), region PMA (memory area of the program), the zero track LI, the scope of the programs of the RA and the target area LO. The area of the PCA is an area to adjust the power of the laser beam emitted from the optical sensor on the optical disk 1. The area of the PMA is an area to temporarily record the address information required for the overwrite operation (namely, the information providing the possibility of recording new data, after the end position of the previous recording). The diameter of the optical disk 1 = 120 mm, which coincides with the format of the CD. However, since there is a CD-ROM, CD-single, which is a CD with a diameter of 8 cm, the diameter of the optical disk 1 can be equal to 80 mm

On Phi is .3 shows the structure of an optical disc 1. Figure 3 depicts the CD-R as an example of the optical disk 1. Assume that the party, which irradiates the laser beam from the optical pickup 3, shown below, towards the bottom side sequentially formed protective film 21, a reflective film 22, the layer 23 of the record and the substrate 24. The reflecting film 22 is composed of a metal material such as Au or Ag. Layer 23 record consists of an organic coloring matter. The substrate 24 is made of synthetic resin with high optical permeability. The substrate 24 can be manufactured, for example, of polycarbonate, in which pre-made groove 25. As organic coloring matter layer 23 records can be used cyanine dye type and dye phthalocyaninato type. As described in the section "prior art", the pre-formed groove 25 is made with "lobularia" in the radial direction of the disk 1, whereby it records the address information (information provision). When the energy of laser light emitted from the optical sensor 3, focuses on pre-made groove 25 (in other words, when laser light is focused by the objective lens of the optical sensor 3), is formed deformed part (Pitta) in the interface between the part to be heated and dissolved organic Kras is the pollutant specific layer 23 recording and substrate 24, which is softened due to heat radiated by the laser light. As a result, in the pre-formed groove 25 of the optical disk 1 is recorded data. When the optical disk 1 from the optical sensor 3 is fed laser light with intensity smaller than the laser light in the recording mode, and the difference between the energy level of the light emitted by the optical sensor 3, and the amount of light reflected by the optical disk 1 is determined by the optical head 3, the data can be reproduced. Information from the optical disk 1 can be played with a CD player and play devices CD-ROM, as well as recording device and playback of CD-R's.

As shown in figure 4 and 5, the pre-formed groove 25 is executed sequentially in the form of a spiral from the field of PCA to LO end zone (on the entire surface of the disk from the inner part to the outer part). The pre-formed groove 25 is made with lobularia to control the rotation of the disk and to form the recording signal. As described above, data is written in the pre-formed groove 25 or between the pre-formed groove 25 and the surface of the disk. The address information sequentially recorded in the form of information lobularia pre-formed grooves 25. To record and address information as information lobularia optical sensor 3 is moved to the desired point in the optical disk 1. Data is written at the position of the optical disk 1.

As can be seen in figure 1, data is transferred from the host computer 10, which is an external device with respect to the drive interface 9 (I/F) (for example, through the SCSI interface (small computer systems)). To the interface 9 connected device 5 encoder/decoder (ENC/DEC). The device 5 encoding/decoding connected to the buffer memory 6. In the buffer memory 6 are written to the data write or data read.

These records are submitted to the device 5 encoding/decoding via the interface 9. In write mode, the device 5 encoding/decoding generates data in the format of CD-ROM. The data in the CD format modulated using EFM-modulation ((eight-to-fourteen modulation) conversion of the primary 8-bit code in a 14-bit to reduce the density of the recording elements on an optical disc and improve noise immunity) and are encoded using encoding with error correction. In playback mode, the device 5 encoding/decoding performs a process of decoding a radio frequency signal coming from block 11 processing a radio frequency signal (which will be described below). The digital data as a result of the decoding process is sent to the main computer 10 through interf is 9. In addition to the ATIP unit 5 encoding/decoding adds the data address in the data record in the form of a sub-code. In addition, the device 5 encoding/decoding adds the data address to the header of the data generated in the format of CD-ROM. Such data addresses are addresses used with ATIP.

These records are submitted to the device 5 encoding/decoding on the actuator 8 of the laser through the compensator 7 records (EQ recordings). The compensator 7 performs a nonlinear transformation to write data so that the recorded bits are the same as on the CD. The degree of offset compensator 7 records adjusted depending on characteristics of the recording layer of the optical disk 1, the shape of the recording laser beam, etc. Information, which represents the optimal power for the optical disk 1 is recorded in the ATIP. In addition, to obtain really the optimal value of the recording power of the optical disk 1 (namely, the output level of laser light emitted from the optical sensor 3)running a test recording using the region PCA. As a result, the test account can be obtained the optimal value of the recording power. After the optimal capacity, the data recorded on the optical disk 1.

The drive laser supplies power to the semiconductor laser device is creation, which is used as the light source of the optical sensor 3 in accordance with the output signal of the compensator 7 entries so that generates a drive signal having a predefined level necessary for recording data on the optical disk 1. The drive signal is supplied from the actuator 8 of the laser semiconductor laser device of the optical sensor 3. Laser light corresponding to the recorded data is emitted from the semiconductor laser device. Thus, the data recorded on the optical disk 1. As described above, the APC (automatic power control) block 11 processing a radio frequency signal controls the laser drive 8 so that the output level of laser light, which is emitted semiconductor laser device is maintained at optimum level. The output signal in the form of light reflected from the optical disk 1, which is removed by the optical sensor 3, is served in the unit 11 of the radio frequency signal processing. The signal lobularia obtained in the form of a push-pull signal generated in accordance with the output signal of the optical sensor 3, is supplied with the unit 11 processing a radio frequency signal in block 12 of the lease.

Unit 11 processing a radio frequency signal contains a matrix amplifier. Matrix amplifier performs the appropriate calculations on si is Nala, remove the photodetector of the optical sensor 3. As a result, in addition to the above-described bipolar signal processing block 11 RF signal generates a signal the error of tracking the position of the head and signal FE focusing errors. Signal the error of tracking the position of the head and signal FE focusing errors are served in the servo control unit 14.

Unit 12 selection address signals of lobularia in the form of a push-pull signal that is passed from block 11 processing a radio frequency signal, a demodulator for frequency-modulated signals through a bandpass filter that passes only the frequency band close to the carrier frequency (22.05 kHz), to obtain a two-phase signal. In addition, the block 12 lease uses a clock frequency derived from the two-phase signal, for controlling the motor 2, the rotation of the disk. In addition, the block 12 lease allocates the data address and control signal of the two-phase signal with a clock frequency. The data address and control signal, selected by block 12 of the lease, served in the unit 13 of the management, based on the microcomputer.

Unit 13 controls the operation of the search using the address data supplied from the block 12 of the lease. In addition, the unit 13 controls the power level of laser light emitted from the optical whom they sensor 3, using the transmitted control signal. Unit 13 controls the drive units, such as the interface 9, the device 5 of the encoding/decoding unit 11 processing a radio frequency signal and the servo control unit 14.

The output signal of the block 12 lease is served in the control block 13. In addition, the output unit 12 of the lease is served in the unit 15 checks for error. As will be described below, the validation block for error determines the presence/absence of errors, using data from the starting time of the zero track and/or data start time end zone control signal, and outputs the result of error detection in block 13 of the control.

In accordance with this alternative embodiment, since the optical disk 1 is a CD-R can be used in various recording methods, such "as the entire disk at once, track at once", "package" and "multiple sessions". In the way that "the entire disk at once", when work begins on the record data on the optical disk 1, it cannot be stopped until such time until it is completely finished. In this way, data is written in the following order: zero track LI, software region RA and the target area LO of the optical disk 1. In the "track at once", first data recorded in the program area. The data is then written to the destination area. On the once, data is recorded in track zero. In the "track at once" each track number, time data start and data end time that is read from the ATIP, written in the pre-formed track 25 in the form of information lobularia. After all data will be recorded in the corresponding track, an entry is made in the end zone. In addition, in accordance with the information which is read from the area PMA, creates the TOC information. The TOC information is recorded in track zero. The way the package immediately a small amount of data repeatedly overwritten. In the method of "multiple sessions" data is written so that multiple sessions is formed in the radial direction of the optical disk 1. Data is written in such a way that each session has zero track and the end zone.

In addition, when reproducing the optical disk 1 at the output of block 11 processing a radio frequency signal is generated RF signal. This RF signal is supplied to the device 5 encoding/decoding. The device 5 encoding/decoding performs the EFM-demodulation, and decoding process in CD format, such as the process of decoding with error correction. After that, the device 5 encoder/decoder performs the decoding process in the format of CD-ROM. Play the produced data, which are formed on the output device 5 encoding/decoding, written in the buffer memory 6. When the device 5 encoding/decoding receives a read command from the host computer 10, the device 5 encoding/decoding transmits the reproduced data written in the buffer memory 6, the host computer 10 via the interface 9.

The synchronization signal frame, the signal is the tracking error and the signal FE focusing errors, which are served from the output of block 11 processing a radio frequency signal and the clock signal frequency, which is output from the block 12 of the lease, are fed to the servo control unit 14. The servo control unit 14 performs the servo control of the tracking tracks and the focus servo for the optical pickup 3, the servo control of the rotation drive of the drive motor 2, the rotation of the disk and the servo motor 4 of the drive.

As described above, the optical disk 1, the pre-formed groove 25 is made with lobularia with frequency modulation (FSK) carrier frequency 22,05 ± 1 kHz. When the frequency-modulated lobularia pre-formed groove 25 is demodulated from the generated push-pull signal corresponding to the output signal of the optical sensor 3, the result is a two-phase signal with a clock frequency of 6.3 kHz. When the scientists of the two-phase signal is demodulated, can be obtained from data with a speed of 3150 bits/second. As described above, since one second is equivalent to 75 frames, one frame data ATIP, which is used as address data consists of 42 bits.

Figure 6 shows the data structure of one frame of data ATIP used as address data of the optical disk 1. The first four bits represent the synchronization signal (SYNC). These 24 bits are part of the description of the address. The last 14 bits are a CRC (cyclic redundancy code). The synchronization signal has a special structure, which no longer occurs in two-phase signal. Decimal digits for the minutes, seconds and frames address data (time information) is denoted using eight bits representing the binary-decimal code. This may be presented addresses to 99 minutes, 59 seconds, 74 of the frame. Assuming that the amount of data in one frame is 2 kilobytes, can be written addresses for approximately 900 megabytes.

The format of the optical disc 1 (CD-R), a combination of four bits for the group M for minutes, S for seconds" and F for "frames" (in practice, these bits are not used (namely, all equal to 0), presents information, which is not the address information (this information is referred to as additional information). As for the older bits of gr is PPI M, which means "minutes", the most senior of its bit is set to "1"when M = "99 minutes". However, in fact, up to the present time, recording duration, commercially available disks is not more than 80 minutes. Thus, the most significant bit group, which indicates "minute", never becomes equal to "1". Additional information except the address information is recorded in the zero track of the LI. In the area of the Republic of Armenia and in the end zone LO only recorded data addresses.

Figure 7 shows the content of the information in combinations of three bits M1, S1, and F1, which are the higher bits in groups of M for minutes, S for seconds, and F for the frames. In other words, the combination of (M1, S1, F1 = 000) is the address of the program area RA and the end zone LO. The most significant bits M1, S1, and F1 and address (M, S, F) program area RA and the target area LO are combined. (M1, S1, F1 = 100) represents the address region PCA region, PMA and zero track. (M1, S1, F1 = 101) represents special information 1 (power records) when the control speed, the application code and the type of the identifier of the disk). (M1, S1, F1 = 110) represents special information 2 (start time zero track). (M1, S1, F1 = 111) represents special information 3 (start time end zone). In addition, as shown in Fig.7, although additional information 1, Ni is sustained fashion information 2 additional information 3 have been reserved, they have not yet been defined. Special information presented M1 = "1", while the additional information from 1 to 3 presents additional information, which is not the address.

In the optical disc 1 (CD-R) the sequence of frames in zero path LI is defined as shown in Fig. As seen on Fig, defined sequence of 30 frames. In frames N, N + 10, N + 20,... (at the interval of 10 frames), is hosting a special 1, special 2, special 3. In frames with other rooms fit the usual address information.

Next will be described a real address, the information presented time, expressed in minutes, seconds and frames. Time information in each area of the program, RA and end-zone LO starts at 00 minutes, 00 seconds 00 frames and sequentially increases from this value. In the zero track LI provides information of time exceeding 90. After 99 minutes, 59 seconds, 74 of the frame time information is set to 00 minutes, 00 seconds 00 frames, and with this value starts the programme area RA.

Characteristics of the standard CD-R, which is an example of the optical disk 1, are defined in the "Orange book", which is a document standard. In the range that satisfies the standard "Orange book", the art, the position of the zero track has some edge. Figure 9 shows the edge of the start position of the zero track LI. In the format in which the duration of playback or recording time of the optical disk 1 is 64 minutes (linear velocity = 1.4 m/s and is constant), as described above, the minimum length of the zero track is LI = (02, 07, 48), and the maximum length of the zero track is LI = (02, 14, 06) in the notation (M, S, F). Thus, the start time of the zero track can be selected from a value that meets the standard above the "Orange book", namely, in the range (97, 45, 69) to(97, 52, 27).

Similarly, in the format, when the duration of the playback or recording time for the optical disk 1 is 74 minutes (linear velocity = 1.2 m/s and is constant), the minimum length of zero track LI is (02, 28, 68) and the maximum length of the zero track LI is (02, 36, 32) in the notation (M, S, F). Thus, the start time of the zero track can be selected from a value that meets the standard above the "Orange book", namely, in the range (97, 23, 43) to(97, 31, 07).

In accordance with this alternative embodiment of the present invention, using the edge of the starting time of the zero track, it is encoded so that its error can be detected automatically. Unit 15 the error-checking (smpeg) determines whether or not there is an error in the starting time of the zero track. For example, encoding is used to detect errors using CRCC (cyclic redundancy check code). In this case, assuming that the polynomial generating g(x)=x4+x+1 and time information start time zero track T(x)=[M, S, F] (24bit, polynomial 23rd from x). The four least significant bit of the frame F are chosen so that the value T (x) can be exactly divided by g(x) (remainder = "0").

When the above-described coding for error detection, block 15 the error-checking divides the starting time of the zero track on the polynomial generating g(x) and determines equal or no residue 0 so that this can be detected an error in the starting time of the zero track. For example, the value of g(x), which allows to obtain a remainder of 0 is from 0 to F (hex encoding). However, BCD encoding does not represent the values from a to F, with a choice of four low-order bits for the frames F is limited. To resolve this problem previously adopted a rule that, when the value takes one of the digits from a to F, the value is added "6". As a result, the values from a to F in hexadecimal encoding can be converted into values from 0 to 5, respectively.

In another way, in addition to Visio Sanogo polynomial generation, thanks to the polynomial generating g(x)=x3+x+1, selects the lower three bits of the frame F so that the remainder of the starting time of the zero track on g(x) becomes equal to 0. The values from a to F, expressed in hexadecimal encoding can be selected from values ranging from 0 to 7.

In the second example, coding, allowing to detect errors using block 15 the error-checking, digits (8 bits) of the frame F are chosen so that, when each digit of M, S and F start time of the zero track of the sum (modulo 75), the result of addition becomes equal to "0". Module (75) is used, because the numbers of frames are selected in the range of values 00 to values 74. In fact, assume that the start time of the zero track is 97 minutes, 24 seconds, Q frames, where Q is a symbol that represents an undefined value. For example, the following formula is satisfied.

The value that satisfies the formula (1), equal (Q=29). Thus, the value for frames equal to (29 frames). Unit 15 the error-checking performs addition on the above formula (modulo 75) and determines equal or not the result of addition of "0"and determine whether there is or there is no error in the starting time of the zero track.

In the third example, the coding error is detected with p the power unit 15 checks the error the four least significant bit of the frame F are selected so that, when each digit of M, S and F start time of the zero track of the sum (modulo 10), the obtained result becomes 0. In fact, assume that the start time of the zero track is 97 minutes, 24 seconds, 10 frames, the value of the four bits is determined using the following formula.

The value that satisfies the formula (2), equal (Q=7). Thus, the value for the frames becomes equal to (17 frames). Unit 15 the error-checking performs addition on the above-mentioned formula (modulo 10) and determines equal or not the result of adding 0 so that checks whether there is or there is no error in the starting time of the zero track.

Since (module 10) is used as the value for the four low-order bits of the digits of the number of frames can be selected one of the digits from 0 to 9. This is consistent with the requirements of the encoding to determine the manufacturer of the disk OSJ (according to "Orange book Japan") for CD-R. figure 10 shows an example of the requirements for the encoding start time zero track for manufacturers (a, b, C, D, E, F,..., G, H,...I) in accordance with the OSJ. "1st code in figure 10 applies to the format in which the duration of the playback of the disc is 74 minutes, in that time, as "2nd ID" Prim is applied to the format, in which the duration of the disc is 64 minutes. The result of the determination of the manufacturer is used to control the output power of the laser beam in the recording mode for CD-R disc as the optical disc 1.

Figure 10 as the 1st code (from 97 minutes, 24 seconds, 10 frames up to 97 minutes, 24 seconds, 19 frames) are assigned, for example, the manufacturer of E. Similarly, values in the range (0 to 9) for the four low bits of personnel assigned to each manufacturer. Thus, when coding for error detection, thanks to the addition (modulo 10), selects one of the values (0 to 9). As a consequence, coding for error detection is consistent with the requirements of the encoding presented in figure 10.

In addition, the values of the codes OSJ (00 to 04) are assigned to cyanine, which is used as the coloring matter layer 23 entry, while (from 05 to 09) assigned to a phthalocyanine as the organic coloring substance, which is used in the layer 23 entries. To meet the requirements of the encoding OSJ, instead of adding the expressions (modulo 75) or adding expressions (modulo 10), put the expression (modulo 5).

As the fourth example of the coding, allowing to detect the error using the unit 15 checks for error, encoding error detection is carried out is carried out for the starting time of the zero track, which are recorded in the zero track of the LI as a special information 3. When the start time of the zero track is 17 minutes, 50 seconds, Q frames, as in the second example, the value of Q for the frame is selected so that the result of addition by the following formula (modulo 75) becomes equal to "0".

The value for the frames, which satisfies the formula (3), equal (Q=08). Thus, the information of time of 17 minutes, 50 seconds, 08 frame is recorded as the start time of the zero track. Of course, the start time of the zero track is a value that does not exceed the value specified in the physical standard CD-R or similar technical conditions. Software error RA depends on the value of start time end zone. As a result, the recording capacity can be slightly reduced depending on the values of start time end zone. However, since the starting time of the end zones are not affected code manufacturer QSJ and code categories organic coloring matter used for the layer 23 entries, we can say that achieves high flexibility in the selection of the starting time of the end zone.

As a fifth example of the encoding, which allows the detection of errors using the unit 15 checks the error, is used as the starting time zero is Orochi, and start time end zone. When the start time of the zero track is 97 minutes, 24 seconds, 10 frames and start time end area is 17 minutes, 50 seconds, Q frames, the value of Q frames is chosen so that the result of addition by the following formula (modulo 75) becomes equal to "0".

The value for the frame start time end zone that satisfies the formula (4), (Q=27). For the detection of errors is determined, equal to or not "0" the result of addition of the starting time of the zero track and start time end zone, which is read from the optical disk (modulo 75).

Next will be described a sixth example of the encoding, which allows the detection of errors using the unit 15 checks for error. In the sixth example, in addition to the starting time of the zero track and/or start time end zone, use the constant K, which contains the drive recorder or player). Assume that the starting time of the zero track is 97 minutes, 24 seconds, 10 frames, the start time of the end zones is 20 minutes, 15 seconds, 34 frame, and K = 25, the result of the addition of the following expressions is equal to 225.

97+24+10+20+15+34+25=225

In other words, it selects the value for the numbers of frames start time end zone. If the result of addition becomes equal to the 225, using only one value of the numbers of frames, the value of the seconds digits. When the read start time end zone, defined, equal or not the result of addition of 225 so that when it is determined whether there is an error in the starting time of the end zone. Selected "225", because in this case the result of the addition is equal to 0 when the addition (modulo 75). As in the above example, can be used in addition (modulo 75). Module (75) is that the result of the addition can be accurately divided. That is different from the case when the result of addition is equal to "225".

In the alternative, can be used two or more types of coding to detect errors in the address information, such as the start time of the zero track, which can be used instead of one type of encoding errors. For example, when adding the expressions (modulo 10) and adding the expressions (modulo 75), can be generated by two types of address information, the result of addition which becomes equal to "0". In relation constants To drive, when it represents two types of constants K1 and K2, can be generated by two types of address information.

In addition, in the above examples are all digits, or bits of address information, such as the start time of the zero track. One is to can execute the encoding error is detected by passing a block address information (namely, values youngest numbers of personnel in information time). In fact, for example, using the start time of the zero track and start time end zone, assuming that the value of the low numbers of frames starting time of the zero track is always equal to "0"may be an encoding error is detected.

Next will be described a seventh example of the coding error is detected using unit 15 checks for error. In the seventh example, each digit of M, S and F start time of the zero track is processed independently. Each digit is multiplied by a predefined factor. In other words, the start time of the zero track is represented by two digits in BCD encoding. Minutes (M) start time zero track are represented by integers (M1iM2i) two digits. Minute (S) start time zero track are represented by integers (S1i, S2i) two digits. Frames (F) the starting time of the zero track are represented by integers (F1i, F2i) two digits. As expressed by the following formula, each digit of M, S and F start time of the zero track is processed independently. Each digit is multiplied by a predefined factor, and then they are added together. F2iis determined so that the result of the calculation modulo z becomes equal to "0".

In this case, the coefficients a to f can be the same or different from each other. Alternatively, some of the coefficients a to f can be the same. We can assume that the second and third examples are special examples of expressions represented by the above formulas (1) and (2). In other words, we can assume that the second example is an example in which in the formula (6), the coefficient a is equal to "10", the coefficient b is equal to "1", the coefficient C is equal to "10", the coefficient d is equal to "1", the coefficient e is equal to "10", the factor f is equal to "1" and the z-factor is "75". Similarly, we can assume that the third example is an example in which all the coefficients a to f is equal to "1", and the z-factor is equal to "10".

In the eighth example, the coding error is detected with the help of block 15 the error-checking is an example in which each digit of M, S and F start time end zone is processed independently, and each digit is multiplied by a predefined factor. In other words, the start time of the final zone is represented by two digits in BCD encoding. Minutes of the starting time of the end zones are represented by numbers (M1aboutM2about) two digits. Seconds start time end zones are represented by numbers (S1o, S2 ) two digits. Frames start time end zones are represented by numbers (F1o, F2o) two digits. As expressed by the following formula, each digit of M, S and F start time end zone is processed independently. Each digit is multiplied by a predefined factor. F2ois determined so that the result of addition modulo z becomes equal to "0".

Can be used as the start time of the zero track, and start time end zone. In this case, minutes of the starting time of the zero track is represented by numbers (M1iM2i) two digits. A second start time of the zero track is represented by numbers (S1i, S2i) two digits. Frames start time of the zero track is represented by numbers (F1i, F2i) two digits. Minutes of the starting time of the end zones are represented by numbers (M1aboutM2about) two digits. Seconds start time end zones are represented by numbers (S1o, S2o) two digits. Frames start time end zones are represented by numbers (F1o, F2o) two digits. As expressed by the following formula, each digit of M, S and F start time zero track and each digit of M, S and F start time end zone are processed independently. Each digit is multiplied by the advance, and the e specific factor and then they are folded with each other. F2iand F2oare determined so that the result of addition modulo z becomes equal to "0".

In accordance with one alternative embodiment of the present invention, the detection unit 15 checks the error is fed to the control block 13. Unit 13 controls the operation of the record, or operation of the playback drive in accordance with the result of the detection unit 15 checks for error. The control block 13 may be controlled such work in different ways.

In the recording mode, the optical sensor 3 reads information from the zero track LI loaded optical disc 1. In addition to the normal operation of the CD-R, block 15 the error-checking checks for errors using the address information or using as the address information, and the constant K. When the result of the determination unit 15 checks the error is that the address information contains an error, the control block 13 prohibits the writing of data in the scope of the programs of the RA of the optical disk 1. In contrast, when the result of the determination unit 15 checks the error is that the address information does not contain an error, the control block 13 is allowed to write data into the show RA of the optical disk 1. When the control block 13 prohibits the writing of data into the show RA of the optical disk 1, block 13 control you the indicates the message is displayed on the display 16 of the actuator, which represents that the data cannot be written, because of what was found error. In other words, only when the address information does not contain an error, the data can be recorded on the optical disk 1.

Similarly, in playback mode, the error on the downloaded disk 1 is checked in the same manner as in the recording mode. When the result of the determination unit 15 checks the error is that the address information that is read from zero) LI loaded optical disk has an error, the unit 15 checks the error prevents playback from the optical disk 1 of the written data. In contrast, when the result of the determination unit 15 checks the error is that the address information does not contain an error, the control block 13 performs such a control optical sensor 3, which allows the playback of data recorded on the optical disk 1. In other words, only when the address information which is read from the optical disk 1 does not contain an error, the data recorded in this field programs the RA of the optical disk 1 can be reproduced. When reproduction of the optical disk 1 is prohibited, due to the fact that the error was detected address information that was read from the optical disk 1, on the display 16 of the drive displays an error message. As bloomian above, when the address information is detected by the error, except for the process of the prohibition of recording/playback of the loaded optical disc 1 loaded optical disk 1 can be forcibly discharged from the device drive. At this point, the display 16 may display an error message.

As the optical disk 1, the optical disk recording capability (for example, CD-R) can be recorded and played back in various recording devices and/or playback. Some users want to use a cheap, commercially available CD-R discs, which can have some problems. From this point of view, the device recording and playback, which can record and reproduce data to/from CD-R discs, can work differently when an error is detected in the recording mode and playback mode.

As an example of work in record mode and playback when there is an error in the starting time of the zero track or the like (for example, address information of the starting time of the zero track address information start time end area, the address information of the starting time of the zero track and start time end zone, or address information that represents the positions of certain data recorded in the field program RA), although it will be prohibited for isimat data loaded on the optical disk, will be allowed to reproduce data from the loaded optical disc. In other words, there are situations where, although the read address information has an error, the data were recorded on the loaded optical disk using another device. When an error is detected as described above, if the loaded optical disc is prohibited to reproduce the data, although the data were recorded on this disc, these data will not play at all. To solve this problem if an error is detected in the address information such as the start time of the zero track will be banned from writing data to the loaded optical disc. However, be allowed to reproduce data from the loaded optical disc. The operation of recording and reproduction are controlled by the control unit, which controls the operation of the recording device and playback. In the following examples, the device recording and playback is controlled by the control unit of the device.

As another example, the work in record mode and playback when there is an error in the address information, such as the start time of zero tracks on the loaded optical disc, the data will not be recorded on the loaded optical disc. In addition, when data are reproduced with loaded) the ski drive, displays the error message on the device display to alert the user that there is a high probability of errors. You can play back data from the loaded optical disc. For example, when data is recorded on the loaded optical disc, if an error is detected in the address information such as the start time of the zero track, the error message "this disc there is a risk of error" may be displayed on the display device. May be generated by an acoustic signal. Can light up a light bulb or similar device. Thus, the user is warned about the error. In addition, it is prohibited to write data in the loaded optical disk. Thus, when the error message appears on the display or similar device, the user can know why the data cannot be recorded on an optical disk. As another example, the work in record mode and playback, if there is an error in the address information such as the start time of the zero track of the loaded optical disc when data is recorded and reproduced to/from the loaded optical disc, the user is warned about the error. However, the data is allowed to record and playback to/from the loaded the frame of the optical disk. For example, some users want to use commercially available, cheap optical drives, an error may occur in the recording mode and playback mode. For these users, when an error is detected in the address information of the loaded optical disk unit, a display device such as a display, may display an error message "it is Not recommended to use this drive". In the alternative, may be generated by an acoustic signal. Alternatively, can light up a light bulb or similar device. Thus, before the operation is performed on the recording or playback after the optical disk is loaded, the user will be warned. However, you can record and play back data. Thus, such users can use cheap disks, which are commercially available, even if there is a risk of error.

As another example, the work in record mode and playback when there is an error in the address information such as the start time of the zero track, which is read from the loaded optical disk in the recording mode, the user is warned in the manner described. However, it is permitted to write data to zag is Jenny optical disk. In addition, it is permitted to reproduce the data from the loaded optical disc. In this case, users can use a cheap, commercially available discs for which likely the occurrence of a problem such as an error in recording or playback. In this example, when data is reproduced from the loaded disk, because the error message is not displayed on the display unit such as a display device, users will not receive unnecessary information.

In addition to detecting errors in the address information such as the start time of the zero track, which is read from the optical disk 1 can be made in the definition of the loaded optical disc 1. In other words, even if the address information can correctly be read from the loaded optical disc 1 when the result of error detection code error detection of the address information read from the loaded optical disk 1 does not satisfy the condition of absence of errors, it is determined that the address information that is read from the loaded optical disk 1 that contains the error. In other words, it is determined that the optical disc, the address information contains an error, is not required by the drive. As a result, in accordance with the read address information can produces is by definition a loaded disk.

In other words, the optical disk 1, a suitable device for recording and playback, the address information such as the start time of the zero track, pre-recorded on the optical disk 1 so that the value calculated according to one of formulas (1)to(8), becomes a predetermined value. After the optical disk is loaded into the recorder and playback, it reads the address information such as the start time of the zero track, with the loaded optical disc using the optical pickup 3, calculates the read address information and determines whether or not the loaded optical disc is suitable for a device in accordance with the result of the calculation (namely, matter or contains no information address error). When a certain result represents that the loaded optical disk is an optical disk suitable for use with this device, it is allowed to write data in the program area RA of the loaded optical disc 1. In contrast, when the result of determination is that the loaded optical disk is an optical disk suitable for use with this device, it is prohibited to write data to the loaded optical disc. When it is determined that the loaded optical disk is not) the sky disk suitable for use with this device, on the display unit such as the display 16 of the actuator may display a warning message such as "Not recommended to use this disk. Caution with its use". In the alternative, may be generated by an acoustic signal. Alternatively, can light up a light bulb or similar device. As a result, the user will be warned.

Similarly, when the optical disk is loaded in the device, the address information such as the start time of the zero track is read from the loaded optical disc. The address information that has been read from the loaded optical disk is calculated in accordance with one of the above formulas (1)to(8) so that it is determined whether or not the loaded optical disk suitable for use with this device. When a certain result represents that the loaded optical disk is an optical disk suitable for use with this device, is permitted to reproduce the data from the loaded optical disc. In contrast, when a certain result represents that the loaded optical disk is not suitable for use with this device, it is prohibited to reproduce data from the loaded optical disc. When the result of determination is that the boot is part of the optical disk is the optical disk, suitable for use with this device, on the display unit such as the display 16 of the drive can display a message such as "This disc is not recommended. Caution with its use". Alternatively can be used by an acoustic signal. Alternatively, can light up a light bulb or similar device. As a result, the user will be warned.

Optical disk with recording capability (for example, CD-R) as the optical disk 1 can be recorded and played back on a variety of devices recording and playback. Knowing that cheap commercially available discs may not be suitable for use with this device, some users, however, may want to use them. From this point of view, when the result of determination is that the loaded optical disc is not a disc suitable for recording and playback, which records and reproduces data on/from the optical disk, CD-R, the device may work differently in the recording mode and playback mode.

As an example of the operation in the recording mode and the playback mode, when the result of determination is that the loaded optical disk is not a disk suitable for use with this device, when the result of the determination, according to stuudy starting time zero track or similar information (for example, the address information of the starting time of the boot track, the address information start time end area, the address information of the starting time of the boot track and start time end area or the address information that represents the positions of certain data recorded in the program area), represents that the loaded optical disk is an optical disk suitable for use with this device, it is prohibited to write data in the program area of the loaded optical disc. However, it is permitted to reproduce the data from the loaded optical disc. In other words, even if the loaded optical disk is an optical disk suitable for use with this device, the data can be written to it on another device. Thus, if the data must not be recorded on the optical disk, which is not suitable for use with this device, it should be possible to reproduce the data on the original device. This reduces performance. However, when the result of determination of the corresponding address information, such as start time, boot tracks, represents that the loaded optical disk is an optical disk suitable for the device, will not be allowed to write new data to the loaded optical disc. Instead this is th, it is permitted to reproduce the data from the loaded optical disk.

As another example, when the result of determination is that the loaded optical disk is an optical disk suitable for the device, when the result of determination corresponding to the address information, such as start time boot tracks read from the loaded optical disc, represents that the loaded optical disk is an optical disk suitable for devices, data must not be recorded on the loaded optical disc. In addition, when data is reproduced from the loaded optical disc, on the display unit or similar device device displays an error message. The user is warned of this message, which represents that the loaded optical disc, probably, cannot be used. However, the data, however, allowed to reproduce. For example, in the recording mode, when the result of determination corresponding to the address information of the starting time of the boot track or similar information which is read from the loaded optical disc, represents that the loaded optical disk is not a disk suitable for use with this device, on the display unit or similar device, the device may display p is eduprise message, such as "This disc is not recommended. Caution with its use". Alternatively, can be generated by an acoustic signal. Alternatively, can light up a light bulb or similar device. As a result, the user is warned. In addition, it is prohibited to write data to the loaded optical disc. When you see this error message, the user can know the reason why data cannot be recorded on the loaded disk.

As another example, when the result of determination is that the loaded optical disk is an optical disk suitable for use with this device, when the result of determination corresponding to the address information such as the start time of the boot track or similar information represents that the loaded optical disk is an optical disk suitable for devices that alert the user enters in the recording mode and playback mode. However, it is permitted to write data to the loaded optical disc, and play with him. For example, knowing that a commercially available, cheap hard drives often have the problem of error in recording mode and playback mode, some users, however, can use them. In the case when the optical disk is not suitable for use with this device, uploaded, in accordance with the address information that is read from the loaded optical disk, a display unit or similar device may display an error message such as "This disc is not recommended. Caution with its use". Alternatively, can be generated by an acoustic signal. Alternatively, can light up a light bulb or similar device. As a result, the user is warned about this. However, the data is allowed to be recorded on the loaded optical disc, and play with him. Thus, such users can use cheap disks, knowing that there are certain risk of error.

As another example, when the result of determination is that the loaded optical disk is an optical disk suitable for the device, when the result of determination corresponding to the address information, such as start time boot tracks or similar information which is read from the loaded optical disc, represents that the loaded optical disk is not a disk suitable for the device in write mode, the user is warned videoporn the m way. However, it is permitted to write data to the loaded optical disc. In addition, it is permitted to reproduce the data from the loaded optical disc. In this case, some users can use cheap, commercially available disks, which can be a problem for the error. When data is reproduced from the loaded optical disk, because the error message is not displayed, the user will not be troubled by excessive messages.

In addition, depending on the type of the optical disk loaded in the device electrical characteristics, such as characteristics of the servo, mechanical characteristics or optical characteristics can be changed and optimized. As described above, the error is detected, the address information in accordance with the present invention can be used to determine one of the many types of drives. Using the definition of the disk, in accordance with the error detected from the address information, if the drive has problems, can change the electrical characteristics of the servo, mechanical characteristics or optical characteristics of the device to work with the loaded optical disk.

In General, in addition to the basic technical conditions, the above standard for CD-R disk, etc. which determines some tolerances for different reference values, such as the degree of eccentricity and track pitch, to compensate for production tolerances, etc. drives. On the other hand, a specific version of the application disk CD-R requires more stringent specifications than the tolerances on the value of eccentricity and track pitch. For example, portable sound recording and reproducing device, and portable video and photo recording and reproducing device should consider the effects of vibrations, etc. Thus, in this case, the optical disk recording capability as a recording medium (namely, CD-R) may require technical conditions closer to control values. The error is detected, the address information in accordance with the present invention can be applied to determine the optical disk, which satisfies the requirements of portable sound recording and reproducing devices and portable photographing recording and playback devices.

Depending on different applications, such as portable sound recording and reproducing devices, photographing devices and conventional computer drive, you can select various types and materials CD-R that is used as a recordable optical disc, which differ from the desired values according to the article the penalties eccentricity and step tracks. In this case, when the portable video photographing device uses an optical disc (CD-R), which is not suitable for use with this device, a problem may occur. However, portable sound recording and reproducing device can easily be used with an optical disk suitable for use with this device, and optical disk drives, suitable for portable video photographing device. In addition, in a usual computer drive without any problems can be used as an optical disk suitable for portable sound recording and reproducing device, an optical disk, suitable for portable video photographing device and an optical disk suitable for normal computer drive. Thus, combinations of devices and types of disks that are suitable for them can be difficult. However, the method of determining the optical disc in accordance with the present invention, allows you to define many types of disks disk that is not suitable for this device.

The present invention is not limited to the above-described variant embodiments. Various other modifications, exceptions and additions in form and detail may be made without departing from the essence and scope of the present invention. For example, instead addresses tortowych provisions boot tracks and end zones, can be used to address end position of the address information, which determines the length (width). In addition, as well as addresses that define the position of the boot track and the end zone, you can use addresses that define the position of the specific data recorded in the program area. For example, in the boot track of the CD or CD-ROM, recorded data such as TOC (table of contents), the absolute time at which the start of individual movement. Thus, as described above, coding for error detection can be performed for the absolute time at which begins the first movement (namely, the position that begins after two or three seconds after the start position of the program area).

As the above-described CD-R disk, the present invention can be applied to a CD-RW on which is written almost the same information as the CD-R disc, in accordance with the ATIP. In addition, as for the drive with recording capability, the present invention can be applied to disks, read-only, such as CD and CD-ROM. In addition, in the case of CD-R and CD-RW disc, the present invention can be applied to recorded data, without pre-recorded address information, such as ATIP.

Furthermore, the present and the finding can be used for address information, encoded with a binary code, instead of the time information with the binary-decimal encoding (minutes, seconds, frames). For example, the first example of a coding error is detected using the CRCC can be used for addresses with binary encoding. Binary encoding can represent more addresses than BCD encoding, with the same number of bits. In addition, in accordance with the present invention, the address information is encoded so that the error address information such as the start time of the boot track or similar, can be determined automatically. Thus, it can be improved the reliability of the address information. For example, when improved resistance to error starting time boot tracks, the data can be stably recorded and reproduced. In addition, in accordance with the present invention, is not required to apply new codes parity. Thus, the present invention can be applied to the recording media that have been standardized format signal, etc. in Addition, in accordance with the present invention, because the result of error detection is used to determine the media recording device, recording/reproduction can only use the appropriate recording media. In this case, the implementation of the Yaya many types of coding for error detection, can be defined a number of types of the recording media.

In accordance with the present invention, the address information, such as the start time of the boot track is encoded so that may be the definition of the disk. Thus, after determining whether the disk is suitable disk, data can be recorded, reproduced.

FIELD: optical data carriers.

SUBSTANCE: data carrier has data area. The latter has multiple zones, in which code blocks with error corrections are formed and sectors remaining as a result of sliding replacement at the end of zone, number of which is less than necessary for forming of one code block with error corrections. Said sectors are not used for recording one code block with error corrections and are skipped, and said code block with error corrections is formed at the beginning of next zone after skipping sectors of zone noted above. Carrier has additional free space, necessary for skipping sectors remaining at the end of zone during sliding replacement process.

FIELD: data carriers.

SUBSTANCE: to determine origin of data carrier disk, errors are used, which appear during manufacture process of master-disk, and are imparted to later batches. Data from said disk in non-corrected form are read, then data about errors is retrieved. Characteristic information about errors is provided and extracted data is compared to characteristic data, which characterizes all data carriers, manufactured by same source. As a result of correlation of compared data, origin of disk is judged either known or unknown.

EFFECT: higher efficiency of copy-protection measures.
