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： An optical disc includes a disc base plate of a light-transmitting synthetic material having a recess for mounting a magnetic plate, and a holding part, integral with the disc base plate, for loosely holding the magnetic plate mounted in the recess with respect to the disc base plate. It is possible with the present optical disc to prevent distortion of the disc base plate otherwise caused by the difference in thermal expansion coefficients of the two components to inhibit double refraction of the disc base plate otherwise caused by such distortion to maintain good recording/reproducing characteristics.

摘要： A recording and/or reproducing apparatus is disclosed in which informational signals are recorded and/or reproduced by irradiating an optical disc 202 with a light beam from an optical pick-up device 1 through an recording and/or reproducing opening 205 which is formed in a disc cartridge 202 which rotatably houses an optical disc 203. The optical pick-up device 1 which is used for the recording and/or reproducing apparatus comprises a light source and an objective lens 5 for converging the light beam from the light source upon the signal recording area of the optical disc 203. When recording and/or reproducing of informational signal on and/or from the optical disc 203 is performed by the optical pick-up device 1, only the objective lens 5 is moved into the disc cartridge 202 via the recording and/or reproducing opening 205 formed on the disc cartridge 202 to shorten the distance between the objective lens 5 of the optical pick-up device 1 and the disc 203.

摘要： A disk recording/reproducing apparatus for recording data on a disk with addition data recorded in a playback only area of the disk along with recording data having the same data structure as that of data which can be recorded in a recording/reproducing area of the disk, thus making it possible to reproduce the addition data along with the recording data. Compressed data obtained by implementing, by using an ATRAC encoder 13, data compression to successively inputted digital data divided into clusters, with cluster connection sectors longer than an interleaving length provided at connection portions of each of the clusters, to implement interleaving processing of the recording data to record them into a recording/reproducing area of a magneto-optical disk 2, and to reproduce them by using an optical head 3. From a reproduction or playback only area of the magneto-optical disk 2, addition data are reproduced from sectors corresponding to the cluster connection sectors.

摘要： A disc-shaped recording medium for storing compressed audio data which have been recorded thereon by an optical recording apparatus. The inner diameter of a data recording region of the disc-shaped recording medium is in the range from 28 mm to 50 mm. The outer diameter of the data recording region is in the range from 58 mm to 62 mm for an inner diameter of 28 mm, and is in the range from 71 mm to 73 mm for an inner diameter of 50 mm. The disc-shaped recording medium may be used with a small-sized portable disc recording and reproducing apparatus, and can record compressed audio data for playback with a playback time substantially as long as that of a standard compact disc having 12 cm diameter.

摘要： The present invention is concerned with an optical disk reproducing apparatus for reproducing digital data from an optical disk, such as an audio compact disk and, above all, with such apparatus in which a continuous playback output may be produced even when track jump should occur due to vibrations or the like. With the optical disk reproducing apparatus according to the present invention, digital data detected from an optical disk are sequentially written in a RAM for subsequent reading so that data stored in the RAM continue to be read even on the occurrence of the track jump to provide a continuous playback output. On the other hand, the optical disk is reproduced at an increased speed for a predetermined time period after the light spot irradiating the optical disk resets to its original position from track jump to replenish digital data to the RAM.
