<p>Apparatus for use with a compact disc (1) for writing and reproducing data on to or from an arbitrary sector of the disc (1) or rewriting data in the arbitrary sector by allowing selection between an interleave or deinterleave process similar to that in an audio type compact disc and an interleave or deinterleave process of a length corresponding to one recording unit or sector, thereby to make possible sector-completion type encoding and decoding. Upon recording, an encoding circuit (3) provided with an interleave delay circuit (5) effects the selected interleave process. Upon reproduction, a decoding circuit (10) provided with a deinterleave delay circuit (12) effects the required deinterleave process.</p> |
