The invention relates in General to recording information, particularly digital information on the recording media in disc form, such as an optical disk or magnetic disk, hereinafter referred to as "disc". More specifically, this invention relates to a disk drive for recording, which can be used in two or more different recording systems. Especially, but not exclusively, this invention relates to a disk device digital video recording (DVR).

Known from the prior art discs have many concentric essentially circular, track record. The track record may take the form of individual circular tracks or one or more continuous spiral track. Next will be assumed that the disc has a single continuous track, but it will be clear that the invention is not limited to this embodiment. The track is divided into a large number of logical blocks, each logical block has a unique address (i.e. the address block). In principle, each unit is individually addressable, and information can be stored in individual blocks and retrieved from them. In practice, however, this address block is not known to the user. When the user wishes to record information on the disc for recording, the recording device records inform the tion in free, ready-to-use unit. In a particular area on the disk, specially reserved for this purpose, the table is stored, which indicates the location of this information. When retrieving said information reading device reads the table to learn where to look for information. However, it is clear to the user.

In an ideal situation, all the blocks ready to use. In this case, during the process of recording, information is recorded in subsequent blocks, and all blocks are physically adjacent to its neighbors. In practice, however, the drive may show bad blocks, namely blocks, where the record information without defects is not possible or where minor errors cannot be corrected during reading. This corrupted block is no longer suitable for recording. When it's damaged state of a block is known in advance, his address is listed damage, and this can be simply skipped when reading and writing.

However, it may be that the invalid condition is detected only during recording. For this situation it is usual reserve a spare area on the disc for recording. This spare area cannot be addressed by the user and is intended to replace any damaged blocks. Thus, upon detection during recording damaged the second block are recorded in a block of a spare area of the recording instead of the damaged unit. The location or address of a block of substitution used instead of the originally designated unit identified in the replacement file. While read just recorded information, now you can read the complete file, including the information recorded in the block replacement.

In principle, the entry replacement unit replacement spare area is used only with respect to the specified bad block. After recording the data packet in the block of a spare area for recording the following data packets continues in a normal block that follows the corrupted block in the normal recording area. This means that the principle of recording the substitution into the spare area includes two twists of the recording head during recording. Similarly, two jump of the read head is required for reading information. To hold the jump distance is relatively small spare area is in fact distributed in both sections of the spare area along the entire length of the track. It should be noted that the recording head and the reading head can be combined into a single device.

The principle of recording the substitution into the spare area is satisfactory for the case when the information to be saved, are, for example, computer data. For this situation, when the disc may be viewed as a tool p is mate for computer the temporal behavior of the data flow is not critical. Currently, however, the disc is also used as a storage medium for storing audio and/or video (AV) in digital format. During recording as well as during read-only recorded information, an important factor is that the data flow is not interrupted. A relatively short interruption of the writing process or reading process can be controlled by buffering the data stream. However, the races of the read head or write head from the normal recording area to the spare area of the recording back and take a relatively long time even to such an extent that the principle of recording the substitution in the spare area is not suitable for use in situations where important is the behavior of the data stream in real time. Therefore, in the case of applications where the behavior of the data stream in real time is important, usually on the track not reserved spare area. The presence of any section of the spare area would result in the disadvantage that the recording head or the read head, respectively, upon achievement of such section spare area must make a leap over a spare area, which leads to the interruption of the writing process or reading process, is relevant to the military.

Thus, there were developed two important standards: one for use of computer data and one for use of audio/video data. In the first system path contains topics spare area, distributed along the path, whereas in the second system the track is free from such sections of the spare area. The above standards are incompatible. If the disc has been formatted for use in environments where important is the behavior of the data stream in real time, such as the environment, audio/video, such a disc cannot be used for data storage in the computer, as in this application is expected to have a spare region. On the other hand, if the disc has been formatted for use in the computer, the disk can no longer be used in the application, where the importance is the behavior of the data stream in real time, such as the application of audio/video, because of the availability of spare areas, distributed over the length of the track.

The purpose of this invention is a solution to this problem. More specifically, this invention is directed to providing a disk for recording, which can be used in a personal computer or similar system, where required spare area, and the device records the audio/video data or similar system, the de behavior of the data stream in real time is important and it would only be disturbed by the presence of a spare area. An additional objective of this invention is the provision of a method and device for recording information on a disc for recording according to the invention.

These objectives are achieved by providing a recording medium according to claim 1, by providing the method according to any of items 10, 12, 13 or 14, and by providing the device according to item 15.

According to an important aspect of this invention, the disc contains both the scope of the user, and a spare region, but the spare area is located at the edge of the area available to the user, so that the area available to the user is not interrupted any spare area.

These and other aspects, features and advantages of this invention will be explained in more detail, by way of example, in the following description of preferred embodiments of the invention with reference to the drawings, in which:

figure 1 is a functional block diagram showing a part of the recording devices

figure 2 schematically shows the logical structure of the disk for recording in General,

figure 3 schematically detail shows the logical structure of the disk for recording according to the prior art, and

figa-4C schematically show the logical structure of the disk for recording according to this invention.

Figure 1 is a functional block the scheme, showing part of the device 1 records intended for recording information on the recording medium 2. Next will be assumed that the recording medium 2 is an optical disk for recording and that the device 1 is an optical recording device. However, this invention is not limited in this area; on the contrary, the invention is also applicable, for example, to magnetic recording.

Disc 2 record has the track 3 recording, which is assumed below, is a continuous spiral track. Although this implementation is preferred, the invention is not limited to such implementation; on the contrary, the invention also applies to discs where the track 3 is implemented as two or more spiral tracks, and the disc, track 3 is implemented as a set of individual mutually concentric circular tracks. In the literature, each individual circular track of this type is sometimes called a "path", and in this terminology, the disc would have more than one track. Unless stated specifically otherwise, this distinction is not carried out, and the full length of the recorded space will be indicated below as one track.

To implement a write operation or a read operation, the device 1 has an optical recording/reading head 10 and the rotary disc, which for the sake of simplicity not until the EN and facing head 10. Disk 2 can be placed on a rotary disk and, thus, to obtain rotational movement relative to the head 10, which allows the head 10 to scan the track 3. Information is recorded in the track by means of a radiation beam such as a laser beam 11. Since the process of the optical recording and reading information known per se from the prior art, it will not be explained further here.

Figure 2 schematically shows that the track record 3 contains the logical blocks of 4. Each block has a unique address, which was recorded at the specified address field of this unit. Thus, it is possible to store information directly in the specified location corresponding to the specified address on the disk 2, and, similarly, you can retrieve the information directly from a given location corresponding to the specified address. Figure 2 also illustrates that the numbering consecutive blocks is continuous. This means that if a certain block 4ihas address X, then the following block 4i+1has address X+1.

The writing process and the reading process are controlled by the functional block 12 in the device 1 records, referred to as process control block entries. Unit 12, the recording process control controls the positioning of the head 10 relative to the disk 2, and controls the laser beam 11 to done by the means of the write operation or the read operation in one or more specific addressable logical blocks 4. The device 1 also has a function block 13, hereinafter called the control block distribution. Unit 13 controls the distribution determines where there should be a write operation. More specifically, the control block 13 distribution determines the logical block addresses that will be used for recording. When the user starts the write operation, the block 13 allocation control determines whether there is enough space for recording to disk 2, and which part of the track 3 is writable. Because the block 12 control record and unit 13 controls the distribution is known as such, they will not be described further here.

In principle, information can be written at any place on the track 3. However, not all the track 3 is writable by the user. A predefined region 31 is reserved for saving system information related to the contents of disk 2. This information may include, for example, to the number of files on disk 2, the initial locations of the files, the length of files, file names, etc. This area 31 will be called hereinafter the administrative area. The remaining part of the track 3 is in General available to save the user information. This remaining portion will be called the next physical volume 32 track 3.

In the case of applications where it is important stand the decline in the flow of information in real time, lane 3 contains no spare areas, and the entire physical volume 32 is available as a user. Schematic drawing of figure 2 shows this option. On the other hand, in the application to save files of digital data, when the behavior of the data stream in real time is less important, physical volume 32 contains a lot of spare areas 33, distributed along the length of the physical volume 32. Schematic drawing of figure 3 illustrates this situation. Figure 3 shows only three spare area 331, 332, 333but in practice, the number of spare areas is much greater.

The blocks in the spare regions 33 have addresses and as such are addressable blocks that are physically available in the system. However, the addressable locations in the spare areas 33 are not directly accessible to the user; therefore, each spare area is schematically indicated by the cross in figure 3 and 4. A distinction is made between physical volume 32 volume and a logical volume 34, which is defined as part of the physical volume 32, unused spare area 33. Figure 3 you can see that the logical volume 34 consists of many segments, logical volumes, divided spare areas 33. Figure 3 shows four such segments of the logical volume 341, 342, 343, 344.

Lower than according to what the difference will be made between the logical address LA and the physical address PA. The logical address LA of the addressable unit is the address in the logical volume 34, while the physical address PA is address of the block in the physical volume 32. Because of the availability of spare areas 33 these addresses are not identical. More specifically, addressable blocks within the spare areas 33 do not have addresses in the logical volume and, therefore, they do not have a logical address. Figure 3 the numbering of addressable blocks 4 starts on the left side of the physical volume 32, with a physical address PA=0, whereas the same unit also has a logical address LA=0. The following blocks have addresses 1, 2, 3, .... If we assume that the number of addressable blocks within the first logical segment 341equal to L, then the last block in the logical segment 341has a logical address LA=L-1. The first addressable block in the next logical segment 342has a logical address LA=L. When writing a file that contains more than L units, the following units such file always have sequential logical addresses. However, in the physical volume that is not the case. Physical address PA=L is, in this example, the address of the first addressable block in the first spare area 331. If the first spare area 331contains N blocks, the first addressable unit within the second logical segment 342has a physical address PA=L+N; thus the om, in this case, the logical address LA=L corresponds to the physical address PA=L+N.

It should now be clear that between the logical address LA and the physical address PA, there is a one-to-one; if some block 4ihas a logical address LA=X, then it also has a physical address PA=Y (it should be noted that the reverse conclusion is not true). If this relationship is known, it is possible to calculate the physical address PA of the logical address LA. Further, this relationship is expressed by the following expression. Let LA(4i) specifies the logical block address 4i. Let PA(4i) specifies the physical address of the block 4i. Let PA[LA] specifies the physical address PA of the block with the logical address LA. Then:

PA[LA(4i)]=PA[X]=PA(4i)=Y

Further, the phrase "physically contiguous" is used in relation to part of the track, where all blocks have 4 consecutive contiguous physical addresses. In other words, for each pair of two consecutive blocks 4iand 4i+1within such a physically contiguous portion of the track having consecutive logical addresses LA(4i)=X and LA(4i+1)=X+1, the physical address PA(4i) and PA(4i+1) are also consistent. This is expressed by the following expression:

Using the above definition of the phrase "f is continuous physical" to describe the logical structure of the prior art, shown in figure 3, it should be clear that each logical segment 34iis physically contiguous in itself, but that the logical volume 32 as a whole is not physically contiguous. For example, the last block in the first logical segment 34iwith the logical address LA=L-1, the expression 1 gives:

PA[LA+1]-PA[LA]=(LA+N)-(L-1)=N+1

When the optical disk 2 to record has just been made, he physically contains the track 3, and hence is suitable for recording, but the difference individually addressable blocks, the allocation of addresses for the blocks, the difference between the physical volume and the administrative scope and definition of the spare areas, etc. have not yet been implemented. The process of the so-called formatting is the first time the drive is inserted in the recorder. Depending on the type of a recording device, the device performs a specific type of formatting; if the device forms part of a system for recording audio and/or video data, the formatting will be carried out in accordance with the schematic illustration of figure 2. Drive formatted for audio/video applications, cannot be used to store standard data until the disk has been reformatted, which includes the loss of pre-recorded information. If the first recording device is, for example,a personal computer, the device can offer the user a choice between a format for audio/video applications, on the one hand, and formatting for data storage, on the other hand. If the user selects a format for storing data, the formatting will be performed in accordance with the schematic illustration of figure 3; now the drive cannot be used for recording audio and/or video data until the disk has been reformatted, which includes the loss of previously recorded data.

This invention provides a different type of formatting that allows you to use a disc formatted in accordance with the present invention, in a computer system for data storage, but also in the consumer device to record audio and/or video data. An important aspect is that the drive is formatted in accordance with this invention should be used in an existing device, which means that adaptation recorder or reader is not required. In other words, the format must be compatible with the standardised format for data storage, on the one hand, and also with the standardised format for audio/video applications, on the other hand. This objective is achieved in accordance with this invention by combo receiver is of the spare area with a continuous logical area, as shown in figa-4C.

Figa shows track 3 account that has administrative region 31 and the physical volume 32. Physical volume 32 contains one spare area 36 at the beginning of the physical volumes 3 and one physically contiguous region 37, available to the user. It should be noted that the beginning of track 3 are usually located at the inner edge of this track. The first addressable block of the logical volume 37, having a logical address LA=0, is adjacent to the last block in the spare area 36. Ask that the spare area 36 contains N blocks, the first addressable block of the logical volume 37 has a physical address PA=N. a Disk having a track 3, formatted as shown in figa, can be used to record audio/video files in the logical volume 37 no problems known from the prior art, as shown in figure 3, as the logical volume 37 is a solid volume, not interrupted by any of the spare area. On the other hand, the disk having a track that is formatted in accordance with figa, can also be used to record computer data or the like, as lane 3 contains a spare area 36.

Figv shows a manner similar to the method according figa corresponding to the second variant implementation of the invention. Again, lane 3 contains one spare area 38 and one physically contiguous volume 37, not Prieur is p any spare area. In this case, the spare region 38 is located at the end of the physical volume 32. Thus, the logical address LA=0 for the first addressable block within the logical volume 37 corresponds to the physical address LA=0 the first addressable unit within a physical volume 32, while the first addressable block within the spare area 38 adjacent to the last adisoemarto block within the logical volume 37. Specialist in the art it will be clear that the disk with track 3, formatted in accordance with pigv, can be used to record audio/video files as well as for recording computer data files, as explained above with reference to figa. In both cases described above, files, computer data and audio/video files can be recorded mixed in the same logical volume 37, not interfering with each other.

In the case of audio/video applications disk is full, when the logical volume 37 is full, even if the spare area 36, 38 is not yet complete. Similarly, in the case of computer applications, the disk is full, if full logical volume 37, even if the spare area 36, 38 is not yet complete. But now the disk is also called complete when the spare area 36, 38 full, even if the logical volume 37 is not yet complete. In both cases it may be preferable to fix the replacement value is the area after the initial formatting. In the first embodiment of the invention, illustrated in figa, fix the size of the spare area 36 has direct consequences for addresses of addressable blocks in the logical volume 37, as the location of the logical addresses LA=0 is changed. In other words, after fixing the size of the spare area 36 all addressable locations within the logical volume 37 received another email address. This means that even if their content does not change, in General it is not possible to find their content, since the addresses have changed.

This problem does not occur in the second variant, shown in figv, in which a spare area 38 is placed at the end of the logical volume 37. If the size of the spare area 38 is fixed, addressable locations at the end of the logical volume 37 may be lost. However, all addressable locations within the logical volume 37 remaining after repair of the spare area, still have the same address and the same content as before, so you have already saved files are still available. For this reason, the second option, shown in figv is preferred compared to the first option figa.

The third variant embodiment of the invention combines the first and second variants. In this third embodiment of the invention illustrated in figs, physical volume 32 is physically continuous, yunae logical space 37 with the first spare area 36 at the beginning and the second spare area 38 in the end. In the context of this invention it is important that the logical volume 37 is physically contiguous, and it is not interrupted any spare area.

It should be noted that figa-4C relative memory capacity of the logical volume 37 and spare regions 36 and 38 are not shown to scale; in General, the size of the volume of spare areas is only a few percent of the size of the logical volume 37.

As explained above, the spare area is defined during the first initialization of the disc, i.e. during formatting of the disk. At this point you can query about the user enters the size of the spare areas. A user who is interested only in the preservation of computer data, you may wish to have more space available spare areas than the user who is only interested in the audio/video files. However, to ensure that the drive can always be used to store computer data, and also for storage of audio/video files, in a preferred embodiment, the disk 2 is always the first spare area 36 having a fixed predetermined size, for example, about 1% of the size of the physical volume 52. This ensures that there is always at least some spare area for use in computer applications. During formatting, the user is may wish to have a relatively large spare area, and in this case, a relatively large second spare area 38 is defined, for example, about 5% of the size of the physical volume 32, or the user may wish to have a relatively small spare area, and in this case relatively small spare region 38 may be specified, or the second spare area 38 may be generally omitted. As explained above, the user may later wish to increase or decrease the size of the spare area, and in this case, the size of the second spare area 38 is increased or decreased, respectively, while the size of the first spare area 36 remains unchanged. Therefore, the total size of the spare area can never be equal to zero.

Specialist in the art it should be clear that this invention is not limited to the examples described above, but that certain modifications are possible without going beyond the scope of the invention defined in the attached claims. For example, a path may contain additional reserved areas, the use of which is reserved for specific purposes at the system level or at the application level. Such additional reserved area may, for example, be located at the beginning or at the end of the physical volume 32, or at the beginning or at the end of the logical volume 37. In addition, lane 3 may with erati so-called initial region and the end region, as will be clear to a person skilled in the art. An important aspect in the context of the present invention is that the logical volume 37 no logically adjacent blocks, but the blocks that are physically separated by blocks belonging to the spare area. Preferably, all the blocks are spatially adjacent, namely the logical volume 37 completely free from any interruptions.
