ABSTRACT:
A digital data recording method includes initially designating a recording unit size that is one of a plurality of possible recording unit sizes. Then, the digital data to be recorded is received. The digital data is converted to a sector structure of a predetermined data quantity. An error correction and encoding process, including interleaving, is performed on the converted digital data. Finally, the processed data is recorded onto a disc-shaped storage medium rotated at a constant linear velocity. The disc-shaped storage medium has recorded on it address information that includes repetitions of a plurality of sectors. The recording of the processed data to the disc-shaped storage medium is performed in accordance with the address information and in increments of substantially the designated recording unit size such that each recording unit includes a plurality of sectors, including linking and data recording sectors. The designated recording unit size is not greater than the number of repeated sectors of the address information.
