Abstract: The present invention is characterized in that in a system for accessing an optical card under the control of a general-purpose operating system (OS), the directory format of the optical card is such that directory data items for various types of general-purpose OS are divided into information usable in common in a plurality of different operating systems and control information peculiar to specific operating systems, and then the information usable in common is set in a common directory area, and the control information is set in individual information areas, thereby forming data items in a general-purpose format, and that when the CPU accesses the optical card, the control information suited for the operating system running on the CPU and the data in the common directory area are extracted from the data in the directory in the general-purpose format, and then these data items are recombined into a data format suited for the directory format of the operating system, and when the optical card is written into,

Abstract: A data reproducing apparatus for reproducing information recorded in at least one track formed on a recording medium. The data reproducing apparatus includes at least one track number reading device for reading out the track number of at least one track formed on the recording medium; a designating controlling device for specifying a track having a track number which cannot be read out from among the track numbers of tracks which can be read out, and for designating an information reading starting position on the track; and a data reading device for reading out information on at least one track on the basis of the information reading starting position on the track designated by the designating controlling device.

Abstract: 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.

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.
