A clock generator generates a demodulation clock having the fundamental period calculated by the fundamental period calculation circuit. A phase error amount detecting circuit detects a phase error amount in accordance with a phase difference between the demodulation clock generated by the clock generator and a plurality of pulses including the reproduction target pulses. A synchronizing circuit controls the phase error amount of a generation timing of the demodulation clock by the clock generator to a predetermined value in accordance with the phase error amount detected by the phase error amount detecting circuit so that the demodulation clock generated by the clock generator is synchronized with each of the reproduction target pulses. A demodulator sequentially demodulates the binary reproduced output signal pulses in accordance with the demodulation clock from the clock generator, the demodulation clock being synchronized with each of the reproduction target pulses with the predetermined phase error amount by the synchronizing circuit.

摘要： An optical card of write-once type including a rectangular card-like substrate on which a number of tracks (62) are formed in parallel with each other. In each track, one or more data record sectors (65) are provided and at the same time, one or more alternative information record sectors (66) are provided. When data could not be recorded correctly in a desired data sector in a desired track, the same data is recorded again in an alternative data sector. Then, in an alternative information record sector in the desired track, there in recorded alternative information representing an address of the alternative data sector. The alternative information record sector can be made much smaller than the alternative data sector, so that user area can be utilized efficiently as compared with a known optical card in which one or more alternative data sectors are previously provided. Moreover, the alternative information is recorded in a track in which the data could not be recorded correctly, the access time can be shortened materially as compared with a known optical card in which the alternative information is recorded in a directory track.

摘要： 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.
