    摘要: A recording medium at least having a first recording layer for recording first information and a second recording layer for recording second information. A discriminating signal indicating the playback mode is recorded on at least one of the first and second recording layers provided on the recording medium. The discriminating signal indicates a first playback mode for respectively reproducing the first information recorded in the first recording layer and the second information recorded on the second recording layer, or a second playback mode for calculating the first information recorded in the first recording layer and the second information recorded in the second recording layer to generate playback signals. A reproducing method and apparatus for the recording medium are also provided for reproducing the recording medium.

    摘要: There is disclosed a method for optically recording data in data areas of a disk-like recording medium in which servo signal areas are formed along the track in alternation with data areas. Parity codes for error correction are generated and affixed in at least one direction, that is, in the column or row direction, of a two-dimensionally arrayed data block, and the two-dimensionally arrayed data affixed with the parity codes are supplied sequentially to an optical pickup along any one of the column and row directions so as to be recorded in respective ones of said data areas. The number of the data in the direction of reading of the two-dimensionally arrayed data is selected to be an integer times the data number that can be recorded in each data area provided on said disk-like recording medium, when the former is intended to be greater than or equal to the latter, or the data number that can be recorded in each such data area is selected to be an integer times the number of the data in the direction of reading of the two-dimensionally arrayed data when the inverse relation is intended.

    摘要: An optical disc having address information recorded in a wobbling manner is arranged to record or reproduce data at correct positions. A track is previously formed as a pregroove and is wobbled in accordance with address information. The track is divided into a plurality of sectors. A plurality of sync marks S are formed in each sector, and at least one of the sync marks in one round of the track is formed as a reference mark R different from the other sync marks S. To reduce overhead and to achieve high-density random recording and reproduction, a method may also be used in which one cluster of data is formed of a data area and a link area located between data areas and consisting of two frames, in which each of the data area and the link area has a structure formed of unit frames separated by a sync signal (frame sync), and in which data is recorded or reproduced as unit clusters.
