PURPOSE:To reproduce a sound signal having a high quality by controlling voice digital data to be sent and received for recording and reproducing between a buffer memroy and a disk, so that it is processed at every block unit. CONSTITUTION:A titled device is provided with a read controller 6 for executing a readout operation and control of temporary recording contents of a buffer memory 3, a write controller 8 for writing the recording contents of a disk temporarily in a buffer memory 3' and also executing its operation control, and a disk controller 7 for controlling an operation of the read controller 6 and the write controller 8, and executing control of write and readout operation contents of the disk 4. In case when a PCM-converted signal recorded in the disk 4 is reprouded, the block data of every track unit is written in the buffer memroy 3' of the reproducing side under the control of the disk controller 7 and the write controller 8. In case of this write operation, it is controlled so that a correction of the head address of the buffer memory 3' is executed whenever a track of the disk 4 in which block data to be written is recorded is changed. |
