Abstract

An apparatus for use with a compact disc for writing and reproducing data into an arbitrary sector or rewriting data of an arbitrary sector by allowing the selection of an interleave process similar to that in a music type compact disc or an interleave process of a length corresponding to one recording unit (sector) to thereby make possible sector-completion type encoding and decoding.
