Floppy disc driving apparatus

摘要

A floppy disc driving apparatus includes a floppy disc driver, a head-load driver, an index sensor for generating an index pulse for each rotation of a floppy disc and a signal generator for supplying a drive signal to the head-load driver. It further includes a timer circuit, a head-load flag area and a control circuit for setting the timer circuit to a preset time period longer than the time required for one rotation of the floppy disc in response to an index pulse from the index sensor and setting a head drive inhibition flag in the head-load flag area in response to a signal generated form the timer circuit upon completion of the counting of the preset time period by the timer circuit.
