するフロツピデイスク装置。 In a magnetic head in which a wide core and a narrow core are butted against each other to form a single gap, an erasing current that can magnetize the surface of the floppy disk over the entire width of the wide core is passed through the winding of the head during erasing. A floppy disk device characterized in that the floppy disk surface is magnetized over the entire width of the narrow core by passing a current smaller than the erase current through the winding of the head during writing.
