ABSTRACT:
A CMD (change moduation device) control circuit in an optical card reproducing apparatus comprises a data interval detector which detects a data pit interval from a binary valued signal from a binary value converter and from a row and a column addresses generated by a row address generator and a column address generator, respectively, during scanning of a CMD sensor with a row address generator and a column address generator, a track guide column address detector for detecting a column address of a track guide from the binary valued signal by scanning the CMD sensor, and a decoder for decoding a recorded data from the data pit intervals detected by the data interval detector. In this optical card reproducing apparatus, the decoding is carried out directly from the recorded data pit intervals without moving the optical card during the reproducing operation. Thus, accurate decoding or reproducing of the data can be achieved.
