ABSTRACT:
A floppy disk drive apparatus includes a control signal generating circuit for generating a step signal and a direction instruction signal, head driving section for driving a magnetic head in the radial direction of a floppy disk, and a detector circuit for generating an output signal when the magnetic head locates in the outer limit location of the floppy disk. The detector circuit is inhibited from generating an output signal in response to the direction instruction signal generated for driving the magnetic head in an inner direction of the floppy disk.
