The technical field

The present invention relates to an optical medium for the storage of information and the way information is recorded on the optical storage medium information and/or reproduction of information with her. More specifically, the present invention relates to optical medium for storing information on which data is recorded in the form of lobularia depressions in the whole starting area or a part of the initial region and in the form of depressions on the rest of the optical medium for storing information, and to a method of recording information on the optical medium for information storage and/or reproduction of information with her.

The level of technology

Optical discs commonly used as a medium for storing information in an optical recording devices, and read, whereby the information recorded on the optical disc and/or reproduce information with them without contact with the optical drives. In accordance with the recording capacity of the information optical discs are either compact disks (CD)or digital versatile disks (DVD). In addition, compact discs (CDS) and digital versatile disks (DVD) include recordable compact discs (CD-R) with a capacity of 650 MB, rewritable compact discs (CD-RW), rewritable digital versatile discs (DVD+RW) with a capacity of 4.7 GB, digital versatile disks - operative is a storage device (DVD-RAM), rewritable digital versatile disks (DVD-RW), etc. Disks read-only include compact discs (CDS) with a capacity of 4.7 GB, digital versatile disks - permanent memory (DVD-ROM) with a capacity of 4.7 GB, etc. also developed digital versatile disks with high information density (HD-DVD)having a recording capacity of 20 GB or more.

However, the above-mentioned optical media is standardized by type to ensure compatibility when used in playback devices. Therefore, users want to use optical media, and the cost of acquisition of optical information carriers can be reduced. Attempts have been made to standardize media that have not been standardized. In particular, we have developed formats of new media, so that new media are compatible or consistent with existing media. Meanwhile, in the existing media used method of recording data in the form of depressions or sabuleti grooves. In this case, depression represent a dash of small size, physically formed in the base in the manufacture of the disk, and lobularia grooves are grooves which are formed on the waveform. In addition, the signal from the cavities is detected as trembling, while the signal lobularia grooves detected as push-pull signal.

Figure 1 presents a graph of dependencies push-pull signal and the jitter from the depths of lobularia grooves or depressions. The depth of lobularia grooves, in which the push-pull signal maximum is about 1/8(λ/n). The depth of depression, in which the measured jitter smallest is 1/4(λ/n). Given the characteristics of a push-pull signal and jitter preferably, in the optical medium for storing information having lobularia grooves and depressions, the depth of wobulenzi grooves differed from the depths of the depressions. However, when the depth of wobulenzi grooves is different from the depth of the depressions required separate processes for the formation of wobulenzi grooves and depressions. Therefore, the manufacturing process of the optical medium for the storage of information is difficult. The result is difficult to mass-produce optical medium for storing information. In addition, if the purpose of simplification of the manufacturing process of the optical medium for storing information to make the depth of wobulenzi grooves identical to the depth of the depressions, the characteristics of one of the push-pull signal and the jitter, or both deteriorating and the recording/reproduction of data becomes less effective.

The implementation of the invention

Figure 2 shows schematic view illustrating the physical structure of a recordable optical medium for storing information with high density, disclosed in application No. 2001-23747 on Korea patent filed by the applicant of the present application. Recordable optical medium for storing information with high density includes primary region 110, the region 120 of user data and the horse is ing region 130 and has a track 123 in the groove track and field 125. In this case, user data can be recorded only on the tracks 123 grooves, or both at the track grooves 123 and field paths 125.

When the initial region 110 writes data to read-only on the side walls of the tracks in the groove 123 and/or field tracks 125 instead of the low spots consistently write Vouliagmeni signals 105 and 106, having a certain frequency and shape. In this case, the laser beam L is irradiated on the track in the groove 123 and/or field track 125 for recording data on a track in the groove 123 and/or field track 125 or reproducing data tracks in the groove 123 and/or field track 125. In particular, each primary region 110 and the end region 130 includes a field read-only, in which is recorded information relating to the disk and a recordable area. For disk-related information is recorded in the form of high-frequency lobularia 105 on the recordable areas of the initial region 110. End region 130 and a region 120 of user data include relatively lower frequency wobulation 106 compared with high-frequency lobularia 105. Position 127 designated record label formed in a region 120 of user data.

In the case of an optical medium for storing information having the above-described structure, the read-only data which may be reproduced from the initial region 110 through the use of push-pull channel, and user data can be reproduced from the area 120 of user data through the use of summary channel. In addition, data written in the primary region 110, modulate, using the method of bi-phase modulation, and the user data modulate using the method of modulation (RLL) constraint distances between transitions, which will be described later. Way bi-phase modulation relates to a method of modulation dependent data, does the signal within a specified time interval T. for Example, as shown in figure 3, when the phase of lobularia groove does not change within a given time interval T, the data is represented by a bit "0". When the phase of lobularia groove is shifted within a specified time interval R, the data is represented by a bit "1". In other words, the way bi-phase modulation is a method of writing data depending on changes if a particular signal within a specified time interval, for example depending on whether changes the phase of the signal within a specified time interval. In this case, the described phase modulation of lobularia grooves, but can be modulated to different parameters.

Taking into account the consistency of the modulation method of recording the above-described recordable optical medium for storing information for the purpose of high density with a modulation method write read-only optical medium for storing information according to a variant implementation of the present invention, physical data structure is read-only optical medium for storing information can be represented as follows.

Refer to figure 4 on which the optical medium for storing information according to a variant implementation of the present invention includes a region 13 of the data, which record the user data, the initial region 10, which is formed on the inner side relative to the area 13 of the data, and the end region 15, which is formed on the outer side relative to the area 13 of the data. In the initial region 10, region 13 of the data and in the end region 15 data is written in the form of depressions. In particular, as shown in figure 5, all initial domain 10 or on a part of its data is written in the form of lobularia 8 depressions. In the rest of the optical medium for storing information data is written in plain depressions 9. Lobularia 8 depressions is a depression located in accordance with the waveform. The usual depressions 9 are depressions that are located in a line. Further conventional trench 9 will be called simply "the depressions 9".

Wobulation 8 depressions created on the site of the initial region 10, on which record information (for example, the modulation method, the minimum length of the troughs, the pitch of the track, and so on), which in accordance with the same physical format nevadastate on the storage medium. In this case, the example data in accordance with the same physical format is not modified on the storage medium, is information relating to the storage medium, or information about the copy protection. For example, information relating to the storage medium, includes information about the type of environment for storage, such as a writable disc, only once recordable disc read-only information on the number of recording layers, the information about the recording speed, information on the size of the drive and tperformance, which varies depending on the content storage medium for, for example, information such as the last address area user data area on which data is recorded, written down in the form of depressions 9.

The area in which record data that is in accordance with the same physical format is not modified on the storage medium, can be throughout the initial 10 or a part of it. For example, it is preferable that the section 10A of the information relating to the storage medium, the initial plot area where the record information, which is in accordance with the same physical format is not modified on the storage medium, the data would be recorded in the form of lobularia 8 troughs, and in the rest of the optical medium for the storage of information and data would be recorded in the form of depressions 9.

Lobularia 8 depressions may be of the same period as lobularia grooves previously described recording medium to store information with high density. In this case, the data can be played back using the same playback channel as the playback recordable medium for storing information with high density.

Configuration lobularia 8 depressions can be implemented using a variety of methods. For example, as shown in figa, the configuration of lobularia 8 troughs may be a simple marker configuration formed of the marks 8A and gaps 8b having the same length. When such a simple marker configuration depression carries no information, but the information can be recorded in lobularia. In this case, the push-pull channel can be used as a channel playback lobularia depressions. In the case where the information recorded in the initial region 10, reproduce, using push-pull channel, and the information recorded in the region 13 of the user's data record, using the sum channel, achieving benefits in terms of compatibility can be used the same channels playback, and the playback channels previously described recording medium to store information with high density.

Simple marker configuration is the tsya useful to simplify the manufacturing process of the recording medium. However, using a simple marker configuration, it is difficult to perform tracking method for detecting differential phase used in the tracking system. The method of detecting the differential phase is well known and therefore will not be described.

As shown in figv, with regard to this point, the configuration of lobularia 8 troughs may be a random configuration. Random configuration refers to the configuration in which the marks 8A having a different length, and the intervals 8b having different lengths are random and in which information can be written in the form of depressions and/or in the form of lobularia. If the information is recorded in the form of depressions, and in the form of lobularia, the information can be reproduced from depressions and lobularia through the use of summary channel or two-stroke channel. In addition, to increase the recording capacity, information relating to the storage medium, can be written in the form of troughs, and additional information may be recorded in the form of lobularia, or information relating to the storage medium, can be written in the form of lobularia, and additional information may be recorded in the form of depressions.

As shown in figs, lobularia 8 depressions may be formed in a configuration in which repeats the sequence of labels is within, at least two different lengths and intervals, with two different lengths. For example, lobularia 8 depressions may be formed in a configuration in which repeated marks and spaces having a length of 2T, and the marks and spaces having a length of 5T. In this case, T denotes the minimum length of the label.

Usually the information recorded in the form of hollows lobularia 8 depressions. However, certain information may be recorded in the form of lobularia 8 depressions. To improve the reliability of such information lobularia 8 depressions can be recorded again. As shown in figa to write data, wobulation 20 cavities form at least two times in a row. In this case, lobularia 20 depressions has a period P, and the information of the same type are formed sequentially. When the first and second lobularia depressions create as containing information of various types, the first lobularia depressions may be recorded at least twice in a row, and then the second lobularia depressions may be recorded at least twice in a row. Consequently, a large number of wobulenzi depressions, which includes various information can be recorded at least twice in a row.

As you can see in figv, lobularia 21 depressions may be inconsistently recorded at least twice. In this case, the typical the cavity 23 can be repeatedly formed between inconsistent populatiei 21 depressions. In other words, when forming the first and second lobularia depressions, which includes information of various kinds, can be formed first lobularia depressions and regular hollows and then can be formed by the second lobularia depressions and normal depression. Therefore, when forming a large number of wobulenzi depressions, which includes information of various kinds, among a large number of wobulenzi depressions can be formed by conventional basin. In this case, the mirror sites can replace the conventional basin.

As described above, for smooth playback of all information in the case, even if any one piece of information is defective, lobularia depressions can be recorded again. The result can be improved the accuracy of the information.

Wobulation 8 troughs or depressions 9 is formed on the basis of in advance when manufacturing the optical medium for storing information. If the optical medium for storing information data is written everywhere in the form of depressions in the starting region 10 and region 18 user data depressions can be formed without interrupting the formation of depressions. Therefore, the manufacturing process of the optical medium for storing information can be simplified and the time required for the process can be reduced. In addition, since the optical medium is for storing information according to a variant implementation of the present invention is not lobularia grooves, depression can be made optimal depth. In other words, as described with reference to figure 1, the trench can be formed to a depth at which the lowest jitter, for example to a depth of 1/4 (n/λ).

The modulation method of the data record that is used throughout the initial region 10 or in part the initial region 10, that is, on the section 10A of the information relating to the storage medium, may be different from the modulation method of the data record used in the rest of the field environment to store information. For example, the way bi-phase modulation can be used throughout the initial region 10 or only related to the environment storage area 10A of the initial region 10, while the modulation method (RLL) constraint of the distance between the transitions used in the rest of the field environment to store information.

In the method of modulation (RLL) constraint distances between transitions specify how many bits of "0" exists between two bits of value "1". In this case, the RLL(d,k) reflects the minimum number and the maximum number of bits "0" between two bits of value "1" is equal to d and k, respectively.

For example, data can be recorded on the section 10A of the information relating to the storage medium, in accordance with the method of bi-phase modulation, and the rest of the plot initial oblasti - in accordance with the modulation method RRL(1,7) constraint distances between transitions.

As shown in figa-6S, with bi-phase modulation in the case where within a given time interval there is no change of phase lobularia depressions, recorded data of the bit values are "0" or "1"), and if within a specified interval of time there is a change of the phase of recorded data bits of value "1" (or "0").

In the modulation method RLL(1,7) with the restriction of the distance between the transitions of the minimum number and the maximum number of bits "0" between two bits of value "1" is equal to 1 and 7, respectively. In accordance with the modulation method RLL(1,7) constraint distance between transitions in the case when d=1, data is recorded 1010101, and therefore the label length or gap between two bits of value "1" is equal to 2T. In addition, when d=7, data is recorded 10000000100000001, and therefore the label length or gap between two bits of value "1" is equal to 8T. Therefore, the modulation method RLL(1,7) with the restriction of the distance between the navigation data is recorded as marks and spaces of length 2T and labels and spans a length of 8T. In this case, data is recorded in accordance with the method of bi-phase modulation, contain a cavity and a gap having a length of nT, and the label and the time interval of length 2nT. The value of n may be within the dia is Altanbulag 2≤ n≤4. For example, if n=2, the data recorded in accordance with the method of bi-phase modulation, consist of hollows and spaces having a length of 2T, and of hollows and spaces having a length of 4T. If n=4, the data recorded in accordance with the method of bi-phase modulation, consist of hollows and spaces having a length of 4T, and of the marks and spaces having a length of 8T. Therefore, when n is within the range of 2≤n≤4, all data containing hollows and spaces having a length of nT, and depression and periods of length 2nT included in the range of lengths of marks and spaces formed in accordance with the modulation method RLL(1,7) constraint distances between transitions.

When the period of the marks and spaces formed in accordance with the method of bi-phase modulation, is within the range of the period the marks and spaces formed in the data area of the user, depression, read-only data in whole or in part of the home region and basin data in the field 13 user data can be played back using the phase diagram of the automatic frequency control.

As another example, data can be recorded in whole or in part the initial region 10, for example on section 10A of the information relating to the storage medium using the method of bi-phase modulation, as in the rest of the environment to store info which the latter using the modulation method RLL(2,10) with the restriction of the distance between the transitions.

In accordance with the modulation method RLL(2,10) with the restriction of the distance between the navigation data is written in the form of marks 8A and gaps 8b with lengths in the range of 3T-11T. In this case, the data recorded in accordance with the method of bi-phase modulation, can contain labels 9a and gaps 9b, having a length of nT, and marks 9a and gaps 9b, having a length 2nT, while n may be within the range of 3≤n≤5. In other words, when n=3, data is recorded in accordance with the method of bi-phase modulation, may contain marks and spaces having a length of 3T, or marks and spaces having a length of 6M. When n=5, data is recorded in accordance with the method of bi-phase modulation, include depression and spaces having a length of 5T, and depression and periods of length 10T. The length of the cavities and gaps recorded in accordance with the method of bi-phase modulation, are within the range of 3T-11T, i.e. the range of the length of the user data recorded in accordance with the modulation method RLL(2,10) with the restriction of the distance between transitions. Therefore, as previously described, depression of data in the data area and user data in the initial region can be reproduced using the same phase diagram of the automatic frequency control.

About icandy above method of recording data on the optical storage medium information and/or reproducing data from it can be applied to the storage medium, having one or more information layers.

Although there have been shown and described a few embodiments of the present invention, specialists in the field of technology to which the invention relates, it should be clear that in these cases the implementation of the changes can be made without deviation from the principles of the invention, the scope of which is defined in the claims and its equivalents.

As described above, according to the optical storage medium information and the way information is recorded on the optical storage medium information and/or reproduction of information with her depression is formed on the entire optical medium for storing information. Therefore, the manufacturing process of the optical medium for storing information can be simplified. In addition, depression can be formed to a depth at which is displayed an optimal signal. Therefore, can be improved recording/playback.

In addition, the modulation method of the data record used in all or part of the home region, and the modulation method of the data record used in the rest of the field of optical storage medium for the information, can coincide with the modulation method of recording used on the recordable optical medium for storing information. Therefore, the optical medium for XP is in information read-only, can be compatible with other storage medium. Moreover, can be written more data in comparison with the case where data is written in the form of lobularia grooves, and read-only data recorded in the initial area, and user data can be played back using the same phase diagram of the automatic frequency control.
