Abstract: Data is arranged to one block obtained after a CIRC process so that a predetermined data pattern is recorded into a predetermined portion on a disc. By tracing back an encoding step of a Cross-Interleave Reed-Solomon Code (CIRC), a layout of recording data of one block before the CIRC process for allowing the predetermined data pattern to be recorded into the predetermined portion is obtained. An error correcting process of a CD-ROM mode 1 is executed. If a position of a parity coincides with data for forming the predetermined data pattern, a value of user data of an encoding sequence to form the parity is changed. After error correction encoding of a CD-ROM is executed, encoding of the CIRC is executed to the recording data of one block.

Abstract: Six recording areas, in which coded/digitally-modulated data is recorded, are provided in a data recording area on a disk. The recording areas each have a different offset compensation amount. With those offset compensation amounts, all offset amounts that might potentially be generated in an error correction encoder can be compensated for. Therefore, regardless of an offset amount generated by the error correction encoder, coded/modulated data generated by the existing EFM modulation method and recorded in one of the recording areas is guaranteed to bias the DSV. The length of the recording area is set to a length long enough for the DSV bias effect to be identified.

Abstract: PROBLEM TO BE SOLVED: To record additional data into an area where data have been recorded, while keeping compatibility with an existing format. SOLUTION: A predetermined area of a read-only optical disk, on which content data are recorded by an irregular pit pattern is irradiated with a high-power optical beam and a reflection film is melted, and thus pits are formed in pseudo manner, thereby discrimination data are additionally recorded.

Abstract: PROBLEM TO BE SOLVED: To record additional information to an area where data are already recorded while compatibility with an existing format is being kept. SOLUTION: A predetermined area of an optical disk exclusively for reproduction wherein contents data and the like are recorded by a rugged pit pattern is irradiated with a light beam having high output to melt a reflection film, a pit is imitatively formed and discrimination data or the like are added.
