    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 reproducing apparatus is provided comprising reproducing means (12) for reproducing recording data recorded on an optical disc (1), decoding means (9) for decoding the recording data and detecting error of the decoded data and memory means (6) for transiently storing decoded data from the decoding means (9) at a first rate, wherein the decoding data stored in the memory means (6) are read out at a second rate smaller than the first rate and supplied to an output. A storage region in said memory means (6) is divided into at least a data storage region for storing the voice data and an auxiliary data storage region for storing auxiliary data concerning the voice data. A memory controlling means (8) controls recording and readout in said at least two areas of the memory means (6). It thus becomes possible to write or read plural types of data on and from the same RAM.

    Abstract: A digital recording and/or reproducing apparatus using a recording medium (1), including a first interface circuit (32) for inputting and outputting digital audio data, a second interface circuit (35) for inputting and outputting general digital data excluding the digital audio data, an input connector (31) for inputting the digital audio data and the general digital data, an output connector (34) for outputting the digital audio data and the general digital data, and a recording and/or reproducing device (3,4) for recording and/or reproducing the digital audio data and the general digital data. In recording the digital audio data, the digital audio data input from the input connector (31) is supplied to the first interface circuit (32), and the digital audio data output from the first interface circuit (32) is supplied to the recording and/or reproducing device (3,4) and recorded onto the recording medium (1) by the recording and/or reproducing device (3,4). In reproducing the digital audio data, the digital audio data is reproduced from the recording medium (1) by the recording and/or reproducing device (3,4), and the digital audio data reproduced is supplied to the first interface circuit and output from the output connector (34). In recording the general digital data, the general digital data input from the input connector (31) is supplied to the second interface circuit (35), and the general digital data output from the second interface circuit (35) is supplied to the recording and/or reproducing device and recorded onto the recording medium (1) by the recording and/or reproducing device (3,4). In reproducing the general digital data, the general digital data is reproduced from the recording medium (1) by the recording and/or reproducing device (3,4), and the general digital data reproduced is supplied to the second interface circuit (35) and output from the output connector (34).

    Abstract: A disk-shaped recording medium (2) is disclosed in which data to be recorded thereon are divided into sectors (B0 ... B31) of a predetermined length and are arrayed into clusters (Ck, Ck+1) each comprising a predetermined number of the sectors (B0 ... B31), in which cluster-linking sectors (L1 ... L5) are added at connecting portions of neighbouring clusters, and in which cluster addresses for specifying the clusters (Ck, Ck+1) and sector addresses for specifying the sectors (B0 ... B31) in each cluster are prerecorded on the recording medium (2). A disk recording apparatus and a disk reproducing apparatus for recording or reproducing data on or from the disk-shaped recording medium are also disclosed.
