ブ制御付加回路。A circuit consisting of an up/down counter and a gate circuit, which is connected between a floppy disk side control circuit that does not output a switch filter signal and a floppy disk drive, and is preset to 00 by a track zero signal from the floppy disk drive; Up or down is determined by the direction signal from the floppy disk control circuit, and by counting the step signal, the magnetic head counts the same number as the track number sought, and the counted value indicates a predetermined value. When,
A floppy disk drive control additional circuit configured to output a switch filter signal to the floppy disk drive.
