Abstract: A disc recording apparatus records digital data by an optical head (3) such that time compressed digital data are arranged into a plurality of clusters (C) 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 (C), and the digital data are subsequently interleaved and recorded on a disc-shaped recording medium (2) so that interleaving at the time of data recording on a cluster-by-cluster basis is within the range of the cluster-linking sector. There is also disclosed a disc reproducing apparatus for reproducing digital data so recorded.

Abstract: The appts. records on an optical disc (2) having a memory (14) for storing input digital data compressed from a continuous signal. A signal encoder (15) arranges data from memory (14). The arrangement is multiple clusters at an interval of a set number of sectors annexing to each a linking sector. The cluster data is interleaved for the recording circuit (3, 4). An abnormality detection circuit (30) acts through a controller (7) to inhibit recording upon detection of abnormality. This performs a read out control of the memory.

Abstract: During recording inputted data are sequentially written into a memory (14) at one transfer rate and are read out at a second, higher transfer rate for recording on a record medium (2). The reading of the memory (14) is such that data in a preset first amount are successively read from the memory (14) to always ensure a write space in the memory (14) which has a capacity which is higher than a predetermined second amount when the amount of the inputted data stored in the memory (14) exceeds the first amount. During playback, the recorded data are reproduced at a second transfer rate, which is higher than a first transfer rate required for outputting the reproduced data, and are written in a memory (22). The thus written data are successively read out of the memory (22) as reproduced output data at the first transfer rate. The writing of the reproduced data to the memory (22) is controlled so that a second amount of the reproduced data is written into the memory (22) and an amount of reproduced data, not less than a first amount, is always stored in the memory (22) when the amount of the reproduced data stored in the memory (22) becomes not higher than the first given amount.

Abstract: A disc-shaped recording medium is proposed in which data to be recorded thereon are divided into sectors at an interval of a predetermined length and arrayed into clusters at an interval of a predetermined number of the sectors, and in which clusterlinking sectors are added at connecting portions of the neighboring clusters, in which cluster addresses for specifying the clusters and sector addresses for specifying the sectors in the cluster are prerecorded on the recording medium. A disc recording apparatus and a disc reproducing apparatus for recording or reproducing data on or from the disc-shaped recording medium are also proposed.
