Abstract

PURPOSE: To reduce burden of system control and a host CPU and to construct a formal for a writing block in the circuit for recording and reproducing against the DRAW type compact disk by imparting a think pattern to data.
CONSTITUTION: A generating circuit 435 generating a think pattern imparted at the head of a block format of data is provided. The think pattern is imparted to the data by writing in the think pattern generated by the generating circuit 435 in a specified position of RAM storing writing data.
