摘要： Six record areas for predetermined data that has been encoded and digitally modulated are formed in a data record area on a disc. The record areas have different offset compensation amounts. The offset compensation amounts allow all offset amounts that may take place in an error correction code encoder to be compensated. Thus, regardless of the offset amount generated by the error correction code encoder, encoded and modulated data that has been generated by the conventional EFM modulating system and recorded in one of the record areas securely causes DSV to deviate. Each of the record areas is set to a sufficient length that allows the effect of which DSV deviates to be recognized.

摘要： According to the type of each of a plurality of external input interfaces, it is decided whether digital watermark information is to be detected from data entered via the external input interface. Digital watermark information is not detected from data entered via the external input interface and from which it has been decided not to detect any digital watermark information, but the data is recorded. Thus, there can be provided a data recording apparatus which is not applied with a any heavy load owing to the omission of any unnecessary detection of digital watermark information.

摘要： 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.
