The technical field to which the invention relates.

The present invention relates to a storage medium, the recording method at him and play with him and, more particularly, to a storage medium, on which the updated information is recorded together with the existing information when you change the version number in the physical upgrade or changing the speed of the media recording/playback, as well as to the way you write him/play with him.

Prior art

Typically, optical media (e.g., optical disks) are widely used as storage media devices, optical reader, which record/reproduce information on the optical disc without contact with the optical drives. In accordance with the recording capacity information of optical disks can be divided into compact discs (CDS) and digital versatile disks (DVD). Disks such as CD-R, CD-RW, DVD-RW, DVD-RAM, DVD+RW, etc. are optical discs on which data can be written and from which data may be reproduced and/or deleted.

In addition, when increasing the recording speed of the optical disk and the upgrade disk you want to enable transmission in the drive information for disk-related information related to accounts, and other similar who offered information. In particular, even if the recording speed is increased and upgraded version of the CD, it is useful to ensure compatibility of new disk to an existing disk drive for recording/playback of data on the new disk. In addition, when installing the disc format is preferable to determine the parameters of information relating to accounts, so that it corresponded to existing disc format.

Reliable recording can be performed only when the operating parameters of the drive match the characteristics of the recording corresponding to the recording speed of the optical disk. However, by increasing the write speed of the drive and an optical disc set new standards for drive and optical drive. Thus, the new drives are manufactured so that they meet the new standards. In addition, the updated standards appropriately modify the content related to the characteristics of the recording, such as recording speed, the recording method or the like. In accordance with this to ensure the correct recording of information on the updated disk using an existing drive must be able to read existing drive information related to the versions of the updated disk, which applies to other physical parameters, information on the purpose, related records, or similar information.

However, since it is impossible to predict the version numbers of disks, means recording disk or the like, which will be developed in the future, it is impossible to make the drive, which would allow operation over the entire range of speeds of recording and using the information in future versions of optical discs. Thus, the need to develop a new updated optical disk on which data can be written/from which data can be reproduced by using the existing drive and method of recording/playback.

A detailed description of the preferred option implementation

Figure 1 shows the structure of a data carrier 1000 information, which includes introductory region 10 and the data area 15, in which the recorded user data in the storage media 1000 information. Leadout (not shown) has a data structure similar to data structure introduction region 10, and therefore its description is not provided here. For the example leadin 10 contains an area of 10-1 disk check, zone 10-2 test drive the area 10-3 defect management area 10-5 data disk management and buffer zone 10-6. In addition, the lead-in area 10 further includes a reserved area 10-4, which can be written other information.

When the recording speed is smenyaetsya to improve the speed of data transmission media, the version number and the write strategy used for recording are also changed. However, the version number is not always required to update because of a change in the recording speed. The version number may be changed if, for example, will include some new physical parameters. As a concrete example for a DVD-RW there are rooms with 1.0 and 1.1 versions. The main difference between versions 1.0 and the 1.1 is the copy protection of a DVD-RW, which is a function defined as a physical parameter in the corresponding book format. However, in the existing drive is not possible recognition of the version number of the new drive and determine the recording speed. In this situation, preferably, but not necessarily for the updated information relating to the disk, and information relating to the record, were presented together with the existing information relating to the disk, and information relating to recording so that the drive of the new version can be used in existing and new drives, using existing and new control information, as described in more detail below.

For example, on figa shows information relating to the disk, and information relating to the account, in accordance with the ROM version 1.0. Presents information relating to the disk, and the information relating the Xia recording written in the format of lobularia grooves in the manufacture of the master disk. Before or after the recording of the user data information related to the disc, and information related to the entries recorded in the form of lobularia grooves, copied and transferred to the recording area, at least one of the introductory region 10 and the leadout. Here, the information recorded in the introductory region 10 or the leadout, identical information is recorded in the form of lobularia grooves.

In addition, in the present example, the record information recorded in the introductory region 10 or the leadout, requires the same number of bytes for the data stored in the form of lobularia grooves. In addition, information recorded in the introductory region 10 or the leadout in the same format as the information recorded in the form of lobularia grooves. In accordance with an aspect of the present invention wobulation grooves formed in the region 15 of the user's data. In addition, information relating to the disk, and information related to the account record in the zone 10-5 management data disk in the introductory area 10 in accordance with an aspect of the present invention.

In accordance with an aspect of the present invention the part of the information recorded in the format of lobularia may differ from the part data stored in the introductory area 10 or vivadelli. For example, if you write the address area 15 user data maximum address area 15 user data can be written in the form of lobularia grooves, and the address of the area in which the record data of the user, in essence, ends, can be written in the introductory region 10 or the leadout. In this case, the portion of the data recorded in the form of lobularia grooves may be different from the parts of the data recorded in the introductory region or lead region.

It should be understood that the information relating to the disk, can represent information about the type of disk, including the version number of the disk, disk size, disk structure, data about the manufacturer of the drive or the like. In addition, information relating to the account, can represent information about the recording speed, power play, and information about the structure of the entry, including information on the duration and intensity of the pulse (e.g., Ttop, Tmp, and Tcl). In addition, information relating to the drive, you may include information such as data related to the copyright, author's information, owner information, usage rights, and other similar information.

In figures 2B and 2C shows an example of a record structure that corresponds to the version 1.0 drive figa. Here Ttop, Tmp, and Tcl indicate the time of the initial pulse, the number of pulses and time and the pulse cooling, respectively. In addition, Pw, Pe and Pb denote the capacity of the recording power and erasing power and displacement, respectively. 7T and 3T denotes the minimum length of the record label, and T denotes the reference synchronization period. Also record information about the number of bytes required for recording information related to the account. Based on this information, is able to selectively reproduce only the required data from the data related to the record. As shown in figa, information related to disk write to 0-3 bytes, and information related to recording, 4-9 record in bytes. In addition, from 10 to M bytes can be left as a reserved area. Where M is a number greater than 10.

Information relating to the disk, or information related to the account, change when you change the version number and the recording speed. Here, although not required, it is preferable that the modified information relating to the disk, or information related to the record that was consistently recorded after the existing information relating to the disk, or information related to the record. As shown in figa, information relating to the disk, and information related to the record that matches the current version of the disc (i.e. version 1.0 disc), 0-10 record in bytes, and updated information related to the dis is y, or information relating to account for the new version of the disk or to a new speed record disk write bytes 11) New information relating to the disk, or information related to the account, written in the same format as the existing information relating to the disk, and information relating to the recording to match the existing format. However, the number of bytes used for recording information relating to the disk, and information relating to the account may be changed.

For example, the difference between the structure of a record corresponding version 2.0 disk shown in figures 3B and 3C, and the structure of the record that corresponds to the version 1.0 drive shown in figures 2B and 2C, consists in the following. Parameters such as Ttop, Tmp, and Tcl are identical, but the values of the power Pe2andPe1erase different, resulting in the structure of the erase parameter is added Temp. In this case, preferably, but not necessarily that the information relating to the disk, and information relating to recording on a new version of the CD were recorded in bytes 11-M after bytes 0-10, in which is recorded information relating to the disk, and information relating to account for the existing version 1.0 disk in the same format as the existing version 1.0 disk. In other words, for the new version of disk usage is have the same order of placement information record, as the placement information record for an existing version of the CD. However, as indicated above, if a new version of the CD contains an additional parameter that is not included in the existing version of the disk, the number of bytes may be different. As shown in figa, because the value of Temp is added to the structure of the record in the new version 2.0 disk, information relating to the disk, and information related to the account record in bytes 11-21.

As described above, the new CD updated information relating to the disk, and information related to the account, written in the same format in which the recorded current information relating to the disk, and information related to the record. However, the number of bytes used to record a new (updated) information relating to the disk, and information relating to the account may be different from the number of bytes used to record the existing information relating to the disk, and information related to the record. This happens when you change the settings related to the structure of the record, but it is also possible for other reasons. In addition, the updated structure entries may include the existing structure of the record. In other words, the new structure entry includes the settings of an existing record structure Ttop, Tmp, and Tcl and additionally setting Temp.

ACC is accordance with another aspect, when the same version of the disk can change the write speed. For example, when the disk is version 2.0, and the recording speed is changed from 5 m/s to 3 m/s, since the version of the disk is not changed, the information relating to the disk, does not change, while the change information related to the record. In particular, if the information relating to the disk is not changed, preferably, but not necessarily, the information relating to the drive, not write again, with the disk write only the changed information related to the record. As shown in figa, in bytes 22-28 information related to write, record, and change when you change the recording speed. In addition, user data record using the information related to the disc recorded in 11-14 bytes, and information relating to the recording, the recorded 22-28 in bytes.

Figure 4 shows a sequence diagram of operations explaining the process of recording and/or reproducing user data on and/or from storage media, in accordance with a variant implementation of the present invention. The process will be described with reference to figa. First, at operation S10, the disk loaded in the drive. Here, if the drive is an existing drive, this detects and reproduces the data related to the disk contained in the 0-9 bytes. If iSkoot is a new drive, this drive detects detects and reproduces the information relating to the disk, and data pertaining to records located in the 11-21 or 22-28 bytes that correspond to the new version of the drive. The number of bytes of reproduced data is determined in accordance with the version of the drive. For example, on figa, the number of bytes of data to be reproduced for a given drive can be checked by reproducing data recorded in the fourth byte.

When data is recorded/reproduced by using an existing drive when performing the operation S15 reproduce data corresponding to an existing drive (that is, data written in bytes 0-9). At operation S20, the user data record/reproduce using these data. Alternatively, when the data record/reproduce in the new drive when performing the operation S25 reproduce data corresponding to the new drive (that is, data written in bytes 11-21). At operation S30, the user data record/reproduce using these data. In particular, when data is recorded/reproduced using a new floppy disk, a version of which has not changed and the read speed of which is changed, it is preferable to record/playback Yes the data of the user using the information, related to disc recorded in 11-14 bytes, and information relating to the recording, the recorded 22-28 in bytes.

Next will be described a method of recording/reproduction of information to/from the medium in accordance with a variant implementation of the present invention. Existing information relating to the disk, and information related to the recording, write in a certain area on the storage media. Then the updated information relating to the disk, and/or information related to the recording, which is renewed in accordance with the change of one version of the disk and the recording speed, recording in an area in which existing recorded information relating to the disk, and information related to the record. Here in the example shown in figure 1, the area in which the recorded current and updated information related to the disk, and information relating to the record, represents the area 10-5 management data disk.

In addition, in accordance with a variant implementation of the present invention, the updated information relating to the disk, and information related to the record, consistently record after byte, which contains current information related to the disk, and information related to the record. Here, preferably, but not necessarily, updated information relating to the disk, and the formation related to write, record in the same format as the existing format in which the existing information relating to the disk, and information relating to recording, recorded so that it matches an existing record format.

In aspects of the present invention, the information relating to the disk, and information related to the record can be played on the channel push-pull signal or the total channel. Information, played on the channel push-pull signal can represent the information recorded in lobularia grooves, and information produced by total channel can represent information recorded in the recording area, at least one of the introductory region 10 and the leadout. The information reproduced by the total channel can represent the information recorded in the same format as the label recorded in the area of 15 user data.

Although this restriction is not introduced specifically, it should be understood that the storage medium may include disk media type CD-R, CD-RW, DVD-RW, DVD-RAM, DVD+RW, and DVD next generation with high resolution, such as the disk type Blu-ray and advanced optical disc (AOD) or disks of any other type that may appear or may be created in the future.

Though this is not required in all aspects, it should be understood that the controller 1002 may be a computer on which the method is performed using a computer program encoded on a machine-readable carrier. The computer may be implemented as a chip containing the firmware, or may be a General computer or a special purpose programmed to perform this method.

In addition, it should be understood that to provide a recording capacity of several tens of gigabytes, as a unit 1001 recording/playback, you must use the unit with a small wavelength and high numerical apertures used to record several tens of gigabytes of data on the disk 1000. Examples of such units include, but are not ogranichitelem the m sense, blocks that use light with a wavelength of 405 nanometers, and which have a numerical aperture is 0.85, these units are compatible with disc type Blu-ray and/or these units are compatible with advanced optical disc (AOD).

Although the present invention is, in particular, are presented and described with reference to examples of its implementation, for specialists in the art will understand that various changes in form and details may be made without departing from the scope and essence of the present invention, which is defined in the following claims and its equivalents.
