Abstract: A RECORDING AND/OR REPRODUCING APPARATUS HAVING A MEMORY CONTROLLER WHICH CONTROLS A WRIT-IN AND READ-OUT OPERATION OF DATA INTO THE MEMORY. WHEN DATA ARE RECORDED ON A DISC-SHAPED RECORDING MEDIUM (1) BY THE RECORDING AND/OR REPRODUCING UNIT (3), THE MEMORY CONTROLLER TIME-DIVISIONALLY STORES INTO A FIRST STORAGE AREA OF A MEMORY THE DATA WHICH WILL BE RECORDED ON THE DISC-SHAPED RECORDING MEDIUM (1) BY THE RECORDING AND/OR REPRODUCING UNIT (3) WHILE SIMULTANEOUSLY TIME-DIVISIONALLY STORING INTO A SECOND STORAGE AREA OF THE MEMORY MANAGEMENT DATA FOR THE DISC-SHAPED RECORDING MEDIUM (1) WHICH ARE READ OUT BY THE RECORDING AND/OR REPRODUCING UNIT (3).

Abstract: The disk recording appts. sequentially inputs data to a memory (14) at one transfer rate. This data is subsequently read out at a second, higher transfer rate and recorded to disk (2). The amounts of data read from the memory are set so that there is a writing space in memory. During playback, the recorded data are reproduced at a rate, higher than the rate for outputting the data, and stored in a memory (22). Again the amount of data read always maintains a minimum amount of data in the memory (22).

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 recording and/or reproducing apparatus for a disc-shaped recording medium (1) on which management data to manage recorded data are recorded, including a recording and/or reproducing unit (3), a memory (13) and a memory controller (12). The recording and/or reproducing unit (3) records data on the disc-shaped recording medium (1) and/or reproduces recorded data from the disc-shaped recording medium (1). The memory (13) temporarily stores therein data which are reproduced by the recording and/or reproducing unit (3), and temporarily stores therein data which are supplied to the recording and/or reproducing unit (3) and recorded on the disc-shaped recording medium (1). The memory (13) includes a first storage area for storing data which are produced from the disc-shaped recording medium (1) by the recording and/or reproducing unit (3), or data which are supplied to the recording and/or reproducing unit and recorded on the disc-shaped recording medium (1), and a second storage area for storing the management data for the disc-shaped recording medium (1) which are read out by the recording and/or reproducing unit. The memory controller (12) controls a writ-in and read-out operation of data into the memory. When data are recorded on the disc-shaped recording medium by the recording and/or reproducing unit, the memory controller (12) stores into the first storage area of the memory (13) the data which will be recorded on the disc-shaped recording medium (1) by the recording and/or reproducing unit (3) while storing into the second storage area of the memory the management data for the disc-shaped recording medium (1) which are read out by the recording and/or reproducing unit (3).

Abstract: An optical disc (1) reproducing apparatus including an optical head (3), memory (13), controller (11) and decoder (14). The head (3) intermittently reads digital data in at least two channels L, and R recorded on an optical disc. The memory (13) temporarily stores digital data obtained by demodulating the output data of the optical head (3). The controller (11) controls the reading operation of the optical head on the optical disc (1) based on the amount of the digital data stored in the memory (13). The controller (11) also controls an operation of writing data into the memory and an operation of reading data from the memory so that the digital data output by the optical head (3) are written into the memory (13) at a transfer rate which is higher than the transfer rate at which the digital signals stored in the memory are read out. The is supplied with the digital data for the two channels stored in the memory on a time-division basis. When data are supplied from the memory (13) to the decoder (14), the controller supplies the decoder with a channel identification signal for identifying the channel with which the data received by the decoder is associated.

Abstract: A data reproducing apparatus for reproducing main data from a disc (2) on which a data string comprised of the main data and auxiliary data appended to the main data at intervals of predetermined lengths of the main data, which main data are previously error correction coded input digital data. The main data are separated from data read from the disc (2) and error corrected in a decoder (6). The error-corrected data are stored in a memory (8). The data stored in the memory (8) are continuously read by a readout control circuit (7). Data patterns before and after connecting portions of the main data written in or read from the memory (8) are compared in a comparator (73) and the next data are contiuously reproduced at a time point when the data pattern coincidence is detected in the comparator (73).

Abstract: A memory controller (12) is equipped with a memory data search circuit (35) for carrying out an identifying operation of management information corresponding to a segment located in front of or behind a segment serving as a reference for an editing operation on a recording medium (1) through search and comparison processing of managing information (U-TOC). A system controller (11) does not receive search data and execute the data search but only sets the comparison standard and an initial value and outputs an execution control signal. The editing operation performed reduces wasted space on the recording medium (1), such as a disc, and eliminates "trash areas" which are not addressable in the U-TOC.
