Abstract

PURPOSE:To achieve constitution by an inexpensive IC of a TTL circuit by facilitating readout timing control by starting readout processing a prescribed time behind simultaneous byte data detection during data readout processing of an external storage device. CONSTITUTION:Data on the prescribed capacity of each field, such as the synchronizing byte data write field, data write field, and data buffer field of a sector format, is transferred from the address memory 31 of a format memory controlling circuit 27 to the selector 30 of a timing controlling cirucuit 26 on the start of every field, and the field is discriminated by a coincident signal which shows coincident with the count value data of a readout clock counter 28. Then if the detecting circuit of a readout controlling circuit 11 detects synchronizing byte data during the discrimination of the synchronizing byte data write field, reading operation for data in the data write field is inhibited for a prescribed time after the detection, thus delaying the start timing of reading operation.
