Abstract
PURPOSE:To simplify a circuit constitution and to reduce a cost by using a CRC (Cyclic Redundancy Check) signal as an element to generate a writing error deciding signal by means of the correlation of a correction prohibiting signal and the CRC signal. CONSTITUTION:By counting means 42-45, the CRC signal is counted for a prescribed period, the counting value is compared with a prescribed value, and the error condition of digital data is decided according to the comparison output. Namely, when the counted value of the CRC signal goes to the prescribed value or above set by the counting means 42-45, it is considered that there is no writing errors, and when the counting value does not reach the prescribed value, it is considered that the writing error is generated. Thus, in a writing mode, since the CRC signal, which is not practically in use, is used, the circuit constitution can be simplified and the cost is reduced, as well.
