摘要： Four ECC blocks are recorded in a burst cutting area of an optical disc. Each ECC block is constituted by a BCA content code of 1 byte, content data length of 1 byte, and content data of 14 bytes. Of the BCA content data, the leading 6 bits are used for application ID and the remaining 2 bits are used for block number. Disc ID is stored in the content data. Since the four ECC blocks exist, the optical disc can be managed individually by four applications at the maximum. Thus it becomes possible to manage the same optical disc by a plurality of applications.

摘要： An ECC block is constituted by RS(248,216,33). Of a data length of 216 bytes (symbols), only 16 bytes are allocated to BCA data and the remaining 200 bytes are used for fixed data having a predetermined value. Using the fixed data of 200 bytes and the BCA data of 16 bytes, parities of 32 bytes (symbols) are calculated. Only the BCA data of 16 bytes and the parities of the former 16 bytes of the 32-byte parities, that is, a total of 32 bytes only, are recorded in a burst cutting area of an optical disc. In decoding, error correction processing is carried out by using the fixed data of 200 bytes. The unrecorded parities of 16 bytes are processed as having been erased. Thus the error correction capability in a burst cutting area of an optical disc can be improved.

摘要： A method of digitally recording information on a suitable medium, particularly a CD is described, in which method a recording (11) is made during a recording session. The recording (11) comprises a program portion (20) with the information to be recorded. Prior to recording the program portion (20), a predetermined number of run-in blocks (21, 22, 23, 24) is recorded, and subsequent to recording the program portion (20), a predetermined number of run-out blocks (25, 26) is recorded. During the recording session, an identification code (RID) identifying the recording apparatus used for the relevant recording session is recorded on the medium. In accordance with the present invention, this identification code (RID) is recorded in at least one of said run-in blocks (21, 22, 23, 24) and run-out blocks (25, 26). This provides the possibility of recording a full identification code, even in the case of relatively short recordings.
