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.
