Abstract
PURPOSE:To prevent the breakdown of a sub-block written in a memory, by deciding whether an error correction of a sub-block which does not sent out a write signal to a buffer memory, and does not execute write either can be executed or not, when a sub-block number does not coincide with the value of a predictive register. CONSTITUTION:The titled system is provided with a processor 17 for setting a predicted sub-block number to a predictive register of a buffer control circuit 20, and also, recording the discrepancy of the sub-block number and this sub- block number at every track to a result register, based on the result of detection of an error. In this state, when the sub-block number sent out of sub-block number registers 15, 16 does not coincide with the value of the predictive register, whether an error correction of the sub-block which does not sent out a write signal to a buffer memory 18 and does not execute write either can be executed can be executed or not is decided. In such a way, when the number of the read sub-block is erroneous, it is detected and the breakdown of a data written to a memory can be prevented.
