Abstract

PURPOSE:To perform the error correction processing correctly, by adding an error flag to data after one block of data is read out. CONSTITUTION:A reproduced data WDT is supplied to a delay circuit 42 and a CRC checker 43, and output data WDT' from the circuit 42, a write control pulse WE' from an FF50 to which an error detection signal EDT is inputted from the checker 43, and an address from an address selector 44 are inputted to an RAM40, and data RD is outputted. Data WDT' and a read block address RA are inputted to an ROM51, and a write block address WA is supplied to the selector 44. Input data is supplied from a multiplexer 53 to a memory 52, and an error flag EFLG is outputted through a latch 54. The output and read data RDT are synchronous with each other, and 1 is written in the address. Thus, error correction is performed correctly.
