    摘要: There is provided a disc recording apparatus for recording digital data by an optical unit in such a manner that time compressed digital data are arranged into a plurality of clusters at an interval of a predetermined number of sectors, a cluster-linking sector having a length longer than an interleaving length is provided at each linking part of each cluster, and the digital data are subsequently interleaved and recorded on a disc-shaped recording medium so that interleaving at the time of data recording on the cluster-by-cluster basis is within the range of the cluster-linking sector. There is also provided a disc reproducing apparatus for reproducing digital data by an optical unit in which playback data are obtained by reproducing record data recorded on a disc-shaped recording medium in such a manner that a cluster-linking sector longer than an interleaving length is provided in a linking section of each cluster composed of a predetermined number of sectors, the resulting data is interleaved and recorded on the disc-shaped recording medium, and the playback data are deinterleaved and freed or the cluster-linking sectors so as to be stored transiently in a storage unit. Playback data are written in the storage unit when the data volume of playback data stored in the storage unit becomes smaller than a predetermined volume to maintain a readout space in the storage unit which is in excess of the predetermined data volume. In this manner, data may be read out continuously from the storage unit at a predetermined rate without interrupting the reproducing operation at the cluster-linking sector of the data recorded on the medium.

    摘要: A disk recording/reproducing apparatus and a disk recording/reproducing method wherein a recording disk (1) having an absolute address is provided with a program region (6) and a read-in region (7), data such as play data are recorded on the program region (6), the data are recorded on the read-in region (7) using, as catalog data, a start address data of a data unit region where the data have been recorded and a finish address data, and the data on the program region (6) are reproduced from the catalog data in the read-in region (7). An erase inhibit flag is set to the catalog data for each of the data units, whereby the erase inhibit and the erase enable are designated by the erase inhibit flag for each of the data units for the data that are recorded on the program region (6).
