Description

Description Technical Field [0001] The present invention relates to a recording medium and control information recording method thereof, and more particularly, to a method of recording read/write control information associated with a version of a corresponding recording medium as control information and a recording medium read/write method and apparatus using the recorded control information.

Background Art [0002] Generally, an optical disc on which a large volume of data is recordable is widely used as an optical record medium. Recently, many efforts are made to develop a new high density optical record medium (HD-DVD), on which video data of high definition and audio data of high quality can be recorded and stored, such as a Blu-ray disc (hereinafter abbreviated BD) and the like.

[0003] The Blu-ray disc (BD) as a sort of a next generation HD-DVD technology is the next generation optical recording solution capable of storing data to remarkably surpass the storage capacity of the conventional DVD. And, the technology specifications of global standards for the BD are being established.

[0004] Various kinds of standard suggestions associated with the Blu-ray disc have been proposed. Specifically, various specifications for 2x(or higher)-rewritable Blu-ray disc (BD-RE) following lx-rewritable Blu-ray disc, write-once Blu-ray disc (BD..R), and read-only Blu-ray disc (BD-ROM) have been prepared.

[0005] In spite of the Blu-ray disc of the same series, version of specified contents for the Blu-ray disc keeps being updated to keep up with the technological developments. For instance, disc specifications of the 1x-wri-table Blu-ray disc (BD-RE) keep extending like those of the 2x(or higher)-rewritable Blu-ray disc (BD-RE) do. Hence, the extending specification contents need to be managed as disc version information.

[0006] However, in reproducing a record of a disc of an upper version, even if the read/write is impossible or even if an error occurs in performing the read/write, a read/write apparatus designed suitable for a lower version according to an extension of a disc version keeps retrying the execution of the read/write to bring about a system error.

[0007] WO 03/025935 discloses a method, device and medium for processing information parts of re corded data to provide (restricted) forward compatibility to higher de-vice/medium versions wherein a defined behaviour of an older device is provided, ifit has to handle information of a higher version number than supported by itself.

Disclosure of Invention [0008] Accordingly, the present invention is directed to provide a recording medium and control information recording method thereof that substantially obviate one or more problems due to limitations and disadvantages of the related art.

[0009] An object of the present invention is to provide a method of recording read/write control information associated with a recording medium version as specified information within a recording medium management area.

[0010] Another object of the present invention is to provide a read/write method and apparatus using control information in performing read/write of a recording medium.

[0011] Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0016] Besides, although terms used in the present invention are possibly selected from the currently well-known ones, some terms are arbitrarily chosen by the applicant in some cases so that their meanings are explained in detail in the following description. Hence, the present invention should be understood with the intended meanings of the corresponding terms chosen by the applicant instead of the simple names or meanings of the terms themselves.

[0017] A ’recording medium’ in the present invention includes all kinds of data-recordable media such as an optical disc, a magnetic tape and the like regardless of its recording mechanism. For convenience of explanation of the present invention, a Blu-ray disc (BD) is ex-emplarily taken as an example of an optical disc. Yet, it is apparent that the technical concept of the present invention is applicable to other recording media in the same way.

[0018] ’Control information’ means various kinds of information for disc read/write of the Blu-ray disc and corresponds to ’disc information’ written in a specific area of the Blu-ray disc (BD) or ’physical format information’ written in DVD-RAM/-RW/+RW for example. First of all, ’disc information (hereinafter abbreviated Dl)’ corresponding to a case of a Blu-ray disc (BD) is explained for convenience as follows. Yet, it is apparent that the concept of the present invention is applicable to other discs of different formats (e.g., DVD series) used as the same concept in the same way.

[0019] The present invention relates to a method of recording read/write control information associated with disc version information, The disc version information is preferentially explained and a method of writing the disc version information as ’disc information (Dl)’ within a Blu-ray disc for control information is then explained in detail as follows.

[0020] First of all, regarding ’disc version information’, as mentioned in the foregoing description, a disc version is newly defined each time new specification item is add ed according to the development of disc technology of the same series and a disc author records in a specific area of a disc information that the corresponding disc is prepared by what kind of version, whereby a read/write apparatus (shown in FIG. 7) for read/write of the corresponding disc looks up the disc version information written in the disc for read/write.

[0021] The present invention is characterized in that the disc information is recorded as mutually recognizable specified information between a disc and a read/write apparatus in recording the disc version information as control information (e.g., disc information (Dl)). And, the present invention is characterized in utilizing the disc version information to carry out an efficient read/write control between a read/write apparatus and a disc differing from each other in version.

[0022] FIG. 1 and FIG. 2 show structures of optical discs to which the present invention is applied. FIG. 1 shows a recordable Blu-ray disc (BD-RE/R) of a single layer having one recording layer. And, FIG. 2 shows a read-only Blu-ray disc (BD-ROM) of a single layer having one recording layer.

[0023] FIG.1 is a structural diagram of a single-layered disc having one recording layer according to the present invention, in which disc information (Dl) of a Blu-ray disc (BD) is written as control information in a disc.

[0024] Referring to FIG. 1, a lead-in area is provided as a management area on an inner circumference area of an optical disc of the present invention, whereas a lead-out area is provided as a management area on an outer circumference area of the optical disc. Specifically, a pre-recorded area and a rewritable or write-once area are separate from each other within the inner circumference area of the disc. The pre-recorded area is an area where data was already recorded in manufacturing the disc, whereby a user or system is unable to perform data recording on the pre-recorded area at all. Specifically, in the Blu-ray disc (BD), the pre-recorded area is named a PIC (permanent information and control data) area. And, disc information as information necessary for disc recording and the like is recorded in the PIC area. Yet, the disc information (Dl) of the present invention need not exist within the PIC area necessarily. And, it is apparent that the disc information can be recorded within another management area.

[0025] In a data area, provided are a user data area where user’s real data is recorded and spare areas ISA and OSA to replace a generated defect area. Specifically, a TDMA (temporary defect management area)for recording information of defect and general managements is provided within a management area in such a write-once optical disc as BD-R In case of the re-writable BD-RE, the TDMA is unnecessary to remain as a reserved area.

[0026] FIG. 2 is a structural diagram of a single-layered read-only disc having one recording layer according to the present invention for explaining a location where disc information Dl of the present invention is written.

[0027] In case of the read-only disc, the entire areas of the disc are configured with prerecorded areas. The disc information Dl associated with the present invention can be written in a PIC area within a lead-in area, which is the same of the write-once disc shown in FIG. 1.

[0028] The present invention, as mentioned in FIG. 1 and FIG. 2, intends to provide a method of writing read/write control information associated with the disc version of the present invention efficiently as well as a method of recording write speed information for read/write and write strategy (hereinafter abbreviated WS) information as disc information (Dl) recorded in the pre-recorded area. And, the method of writing the disc information (Dl) of the present invention is explained in detail as follows.

[0029] FIG. 3 is a structural diagram of a PIC area in the disc shown in FIG. 1 or FIG. 2. Referring to FIG. 3, in a Blu-ray disc, ’one cluster1 represents a minimal recording unit, five hundred forty-four clusters gather to construct one fragment as one upper recording unit, and total five fragments gather to form on PIC area.

[0030] Disc information Dl is recorded in a front head cluster of a first fragment IF0. The disc information Dl is plurally written per recording layer and velocity permitted by a corresponding optical disc, and one disc information Dl can include one hundred twelve bytes. Specifically, the above-configured disc information is occasionally called a disc information (Dl) frame. Moreover, the same contents of the disc information Dl are repeatedly recorded in each front head cluster of the rest of the fragments, thereby being capable of coping with loss of the disc information Dl.

[0031] Specifically, in the recordable disc shown in FIG. 1, the information representing the corresponding recording layer and recording velocity and the write strategy (WS) information corresponding to the recording layer and velocity are recorded within each disc information Dl of the recordable disc as well as disc version information. Hence, such information is utilized in read/write of the corresponding optical disc, thereby enabling an efficient read/write.

[0032] Yet, since it is unable to perform a writing operation on the read-only disc shown in FIG. 2, the recording velocity information and the write strategy (WS) information for disc recording will not be included within the disc information Dl.

[0033] A method of recording read/write control information associated with a disc version according to the present invention is explained in detail through various embodiments with reference to FIGs. 4A to 8 as follows. For convenience of explanation, a recordable disc is taken as an example. Yet, as mentioned in the foregoing description, the method is applicable to a read-only disc in the same way as well.

[0034] FIG. 4A and FIG. 4B show a method of writing disc information (Dl) as control information in an optical disc according to a first embodiment of the present invention, in which an area for recording read/write control information therein is separately allocated.

[0035] Namely, an area for recording at least one disc information Dl therein is provided within an optical disc, and an order of each disc information Dl is decided according to its sequence number to be recorded by one byte. For instance, the corresponding information is recorded at a fifth byte within the disc information Dl, is named ’Dl frame sequence number in Dl block’, and is briefly represented by ’OOh, 01 h, 02h,...’. Namely, if the information of the fifth byte is ’OOh’, it means first disc information. If the information of the fifth byte is ’03h’, it means fourth disc information.

[0036] Write strategy (WS) information interoperating with the recording velocity meant by the corresponding disc information Dl is recorded in an area named a ’write strategy parameters’ field by (L~111 )th bytes for the disc information Dl, and read/write control information is recorded in an area named a ’Read/Write operation control’ field by Nth byte as the disc information Dl.

[0037] The ’ReadlWrite operation control’ field is divided into two parts, in which ’recordable version number’ is recorded in first four bits and second four bits are allocated as an area for recording ’read compatibility type number’ therein.

[0038] The ’Read/Write operation control’ field is explained in detail as follows.

[0039] First of all, main version information of a corresponding disc is represented by utilizing the ’recordable version number’ within the ’Read/Write operation control’ field. For instance, if a disc corresponds to versionl.xx (V1.xx), it is represented as ’version number = 000T. If the disc corresponds to version2.xx (V2.xx), it is represented as ’version number = 0010’. And, if the disc corresponds to version3.xx (V3.xx), it is represented as ’version number = 0011’.

[0040] Hence, if a disc of a higher version written as ’version number = 0010 (V2.xx) is loaded in a read/write apparatus of a lower version (V1 .xx), the read/write apparatus of the lower version should not perform a recording on the loaded disc of higher version. So, in case that the higher-version disc is loaded, the read/write apparatus confirms the corresponding disc version information written in ’recordable version information (version number)’ field within the loaded disc not to perform an access operation for performing a write on the corresponding disc but to instantly inform a user and the like that the corresponding disc is not recordable in response.

[0041] Namely, the read/write apparatus is allowed to execute a write on the corresponding disc only if a disc having a write-allowable version is loaded. And, the apparatus reads the corresponding control information from the disc information Dl.

[0042] And, ’Read compatibility type number’ within the ’Read/Write operation control’ field, which is the information indicating whether a reproduction is allowable or not, has a meaning that reproduction of a disc having ’Read compatibility type number’ higher than that of the read/write apparatus is prohibited. So, the read/write apparatus confirms the corresponding disc version infor- mation written in ’Read compatibility type number1 field within the loaded disc not to perform an access operation for performing a write on the corresponding disc but to instantly inform a user and the like that the corresponding disc is not readable in response.

[0043] The ’Read compatibility type number’ preferably has the following restriction conditions.

[0044] Namely, within the same recordable version information (version number), a value of’Read compatibility type number’ is not changed but maintains the same. For instance, it means that ’Read compatibility type number’ of each disc is not allowed to have a different value ’0001’ or ’0010’ in the same recordable version information (’version number = 001T) indicating the version3.xx.

[0045] In other words, if the read compatibility information (Read compatibility type number) becomes Ό00Τ or ’0010’, the version information can represent the same recordable version number (’version number = 041T) that indicates version3.xx (V3.xx, x: 0~9) by taking a value of the read compatibility information (Read compatibility type number) as a reference. Namely, the read compatibility information (Read compatibility type number) should be decided prior to the version information to decide the compatibility, and more particularly, backward compatibility. And, the version information value can be changed as long as the read compatibility information value is sustained.

[0046] A method of deciding the compatibility will be explained in detain with reference to FIG. 8 or FIG. 9.

[0047] FIG. 4B is provided for additionally explaining ’Read compatibility type number” in the same embodiment of FIG. 4A.

[0048] Namely, in FIG. 4A, in case that the recordable version information (version number) corresponds to ’0001’ (V1.xx) or ’0010’ (V2.xx), the same read compatibility information (Read compatibility type number = 0000) is applicable. Yet, in FIG. 4B, in case that the recordable version information (version number) corresponds to ’0001’ (V1.xx) or ’0010’ (V2.xx), read compatibility information (Read compatibility type number = 0000) and read compatibility information (Read compatibility type number = 0001) are respectively applicable.

[0049] Yet, as shown in FIG. 4A or FIG. 4B, in case that the recordable version information (version number) is represented by the higher version information (V1.xx, V2.XX, V3.XX, ...) only and if the case is made impossible to be recordable with the information only, there occurs a confusion in a ’bridge compatible state’.

[0050] Namely, in case that a versionl .1 (V 1.1) is the 1X/2X recording standard and if the standard for supporting a new 4X-speed standard is unable to meet 1X-4X speed overall, the ’bridge compatible state’ means the standard which allows 2X to be partially compatible and 1X-speed to be incompatible by regulating version2.0 (V2.0) as 2X/4X speed and by making 2X to be compatible with the version. (V1.1) standard.

[0051] Hence, in case of the ’bridge compatible state’, it cannot be completely decided as ’write prohibit’ but is made recordable for a partially compatible part. For this, if read compatibility is sustained in designing the read/write apparatus, the read/write apparatus reproduces the disc information (Dl) to read the recording condition (e.g., write strategy, write strategy parameters, etc.) of each velocity and decides whether the velocity is allowable for write. This will be explained in detail with reference to FIG. 8 later.

[0052] FIG. 5 is a diagram of a method of writing disc information (Dl) of an optical disc as control information according to a second embodiment of the present invention, in which an area for recording read/write control information therein is separately allocated.

[0053] Referring to FIG. 5, at least one disc information Dl is recorded within a disc and an order of each disc information Dl is decided according to its sequence number to be recorded by one byte. For instance, the corresponding information is recorded at a fifth byte within the disc information Dl, is named ’Dl frame sequence number in Dl block’ field, and is briefly represented by ’00h, 01 h, 02h,...’. Namely, if the information of the fifth byte is ’OOh’, it means first disc information Dl. If the information of the fifth byte is ’03h’, it means fourth disc information Dl.

[0054] Lth~111th bytes within the disc information Dl are named a ’write strategy parameters’ field. And, write strategy (WS) information interoperating with the recording velocity meant by the corresponding disc information Dl is recorded in the ’write strategy parameters’ field. An Nth byte is named a ’Disc version number (Write compatibility)’ field and write control information of the read/write control information of the present invention is recorded in the ’Disc version number (Write compatibility)’ field. And, an (N+1)th byte is named a ’Read compatibility type number’ field and read control information of the read/write control information of the present invention is recorded in the ’Read compatibility type number’ field.

[0055] Namely, compared to the first embodiment (FIG. 4A, FIG. 4B) according to the present invention, the second embodiment (FIG. 5) according to the present invention extends the ’Disc version number (Write compatibility)’ field to indicate a lower version as well as a higher version.

[0056] The ’Disc version number (Write compatibility)’ field is divided into two parts, in which ’higher version information (1st version info)’ is recorded in first four bits and ’lower version information (2nd version info)’ is recorded in second four bits.

[0057] In case of versionl .0 (V1.0), the ’Disc version number (Write compatibility) field is set to ’0001 0000’. In case of version 1. (V1.1), the ’Disc version number (Write compatibility) field is set to’0001 000T. In case of version3.1 (V3.1), the ’Disc version number (Write compatibility) field is set to Ό011 000T.

[0058] By the above definition, the disc version can be correctly indicated. And, in deciding a write possibility with reference to the version information, the read/write apparatus can enhance its reliance.

[0059] Yet, in the second embodiment of the present invention as well as the first embodiment, the ’Read compatibility type number’ field preferably has the aforesaid restriction condition.

[0060] Namely, in case the higher version information of the recordable version (version number) is like, the value of’Read compatibility type number” is not changed but maintains the same.

[0061] FIG. 6A shows a method of recording disc information Dl of an optical disc as control information according to a third embodiment of the present invention, in which an area for recording Read/Write control information associated with disc version information sustains compatibility with a disc information (Dl) recording method in the 1X recordable Blu-ray disc (BD-RE) which is currently being discussed.

[0062] Referring to FIG. 6A, an 11th byte of disc information Dl is named a ’Disc size / version’ field for recording disc size information and version information therein, ’size information’ is recorded in first two bits b7 and b6, ’Read compatibility type number' is recorded in second two bits b5 and b4, and ’recordable version information (version number (Write compatibility))’ is recorded in third four bits b3 to bO.

[0063] The currently discussed Blu-ray disc (BD) has a size of 12cm only. So, if the disc size information corresponds to ’00b’, it means a case of 12cm. And, the rest is left as a reserved area for a disc size (e.g., 8cm) that will be added as a standard later.

[0064] If the 11th byte is set to ’00 00 0001b’, it means that the disc has a size of 12cm, that the ’Read compatibility type number’ type is ’00’, and that the recordable version information (version number) becomes Ό00Τ.

[0065] In the third embodiment of the present invention (FIG. 6), the read compatible information (Read compatibility type number) has the restriction condition having the same value in the same recordable version information (version number). To solve the problem of the ’bridge compatible state’, the final recordable possibility should be decided with reference to other information (e.g., recording velocity information, etc.) in designing a read/write apparatus. FIG. 6B shows an example modified from FIG. 6A, in which field names are changed in part. Namely, the ’read compatibility information’ (Read compatibility type number’ in FIG. 6A is changed into ’read compatible version information (Read compatible version number)’ and the ’write compatible version information (version number)’ is changed into ’write compatible version information (write compatible version number)’.

[0066] Hence, it is apparent that the above modifications can be developed into various name modifications. For instance, the ’read compatibility information (Read compatibility type number)’ in FIG. 6A is simply modified into ’class information (Class)’ and the ’write compatible version information (version number)’ can be modified into ’version information (Version). In this case, the ’class information (Class)’ becomes information indicating a read-compatible disc version and the ’version information (Version)’ becomes information indicating a write-compatible disc version.

[0067] FIG. 7 is a diagram of a read/write apparatus in an optical disc applicable to the present invention.

[0068] Referring to FIG. 7, a read/write apparatus in an optical disc applicable to the present invention includes a read/write unit 10 carrying out a read/write of the optical disc and a control unit 20 controlling the read/write unit 10. The control unit 20 gives a read or write command for a specific area, and the read/write unit 10 caries out the read/write on the specific area according to the command of the control unit 20.

[0069] Specifically, the read/write unit 10 includes an interface unit 12 performing communications with an external device, a pickup unit 11 directly writing data on the optical disc or reading the data, a data processor 13 receiving a read signal from the pickup unit 11 to restore into a necessary signal value or modulating to deliver a signal to be recorded into a signal to be written on the optical disc, a servo unit 14 reading out a signal from the optical disc correctly or controlling the pickup unit 11 to record a signal on the optical disc correctly, a memory 15 temporarily storing data and various kinds of information including management information, and a microcomputer 16 responsible for controlling the above-described elements within the read/write unit 10.

[0070] Apart from the read/write apparatus, a display device 30 displaying a signal read via the read/write unit 10or providing afinal userwith information via the control unit 20 may be provided.

[0071] FIG. 8 and FIG. 9 are flowcharts of an optical disc read/write method applicable to the present invention, respectively. FIG. 8 preferentially concerns the confirmation of a presence or non-presence of write compatibility, whereas FIG. 9 concerns the confirmation of the presence or non-presence of write compatibility after completion of confirming a presence or non-presence of read compatibility.

[0072] Referring to FIG. 8, once an optical disc is loaded in the read/write apparatus, all management information within the disc is read out to be temporarily stored in the memory 15 of the read/write unit 10. And, the management information is utilized for the read/write of the optical disc. Specifically, the management information stored in the memory 15 includes read/write control information of the present invention. For instance, the read/write control information is provided as disc information (Dl). Thereafter, the microcomputer 16 decides a presence or non-presence of read/write compatibility in the following manner. Specifically, the read-out disc read/write control information can be the information having various names as explained in the first to third embodiments of the present invention. Form the various kinds of information, it can be decided whether the currently loaded disc is recordable (S11).

[0073] Specifically, in the step S11, it is checked whether the recordable case is in ’Bridge compatible state’ (S30) as well as the write compatibility decision (S20).

[0074] Hence, if it is decided in the step S11 that the optical disc is not recordable, the read/write apparatus prohibits further recording (S40). If it is the case that the read is possible from the read compatibility information (Read compatibility), the read is performed on the corresponding disc only.

[0075] And, if it is decided in the step S11 that the disc is the recordable optical disc and that it is not in the ’Bridge compatible’ state, it corresponds to the case enabling a normal recording. So, the read/write apparatus can perform recording with reference to write strategy information (write strategy, write strategy parameters, etc.) within the disc information (Dl) (S80).

[0076] Moreover, if it is decided in the step S11 that the disc is the recordable optical disc and that it is in the ’Bridge compatible’ state, the read/write apparatus confirms from the read compatibility information (Read compatible) whether it is in a read compatible state (S50). In case of the read compatibility, a write condition for each speed within the disc information (Dl) is decided to redecide the possibility of the write compatibility at the corresponding speed (S60, S70).

[0077] According to the result of the step S70, if the write compatibility is decided possible, the read/write apparatus carries out the normal write. If the write compatibility is decided impossible (S40), the read/write apparatus prohibits the data access forwrite, thereby preventing the system errors that may be generated from the disc error or the abnormal write trial.

[0078] Referring to FIG. 9, once an optical disc is loaded in the read/write apparatus, all management information within the disc is read out to be temporarily stored in the memory 15 of the read/write unit 10. And, the management information is utilized for the read/write of the optical disc (S110). Specifically, the management information stored in the memory 15 includes read/write control information of the present invention. Specifically, the read/write control information, is provided as disc information (Dl). Thereafter, the microcomputer decides a presence or non-presence of read/write compatibility in the following manner.

[0079] First of all, it is checked whether the read of the corresponding disc is possible from the ’read-compatible information (Read compatibility) among the read-out control information (S120). If the read is impossible, an access to the data area within the loaded disc is prohibited and the write is prohibited as well (S121).

[0080] If the read compatibility is possible in the step S120, it is checked whether the write of the corresponding disc is possible from the ’write compatible information (Write compatibility)’ among the read-out control information (S130).

[0081] Specifically, in the step S130, it should be decided whether the write-compatible case is in the ’Bridge compatible’ state (S132), if necessary, as well as whether the write is compatible (S131).

[0082] Hence, if it is decided in the step S131 that the optical disc is not write-compatible, the read/write apparatus prohibits a further write and enables the read only (S140).

[0083] Ifthe optical disc is decided as write-compatible in the step S131 and if it is decided in the step S132 that the write-compatible case is not in the ’Bridge compatible’ state, the read/write apparatus decides that it is normally write-compatible to perform normal write within reference to write strategy information (e.g., write strategy, write strategy parameters, etc.) and the like within the disc information (Dl) (S170).

[0084] Ifthe optical disc is decided as write-compatible in the step S 131 and if it is decided in the step S 132 that the write-compatible case is in the ’Bridge compatible’ state, the read/write apparatus checks a write condition for each speed within the disc information (Dl) (S150) and decides again whether the write compatibility at the corresponding speed is possible (S160).

[0085] According to the result of the step S160, if the write compatibility is decided possible, the read/write apparatus carries out the normal write with reference to the write strategy information within the corresponding Dl (S170). If the write compatibility is decided impossible, the read/write apparatus prohibits the write on the disc but enables the read only (S140).

[0086] Accordingly, the read/write apparatus is facilitated to confirm the possibility of the write and/or read of the corresponding disc from the read/write control information of the loaded disc, thereby preventing the system errors that may be generated from the abnormal write/read trial.

[0087] And, if receiving from the microcomputer 16 a notification indicating that the normal write and/or read of the loaded disc is not possible the control unit 20, the control unit 20 preferably notifies an announcement message, which indicates the write and/or read is impossible, to a user via the display device 30, if necessary.

Industrial Applicability [0088] It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the inventions.
