FLOPPY DISK DRIVER

PURPOSE:To prevent a magnetic head from generating a malfunction to e generated at the positioning on the 2nd area when power is turned on and to position the magnetic head on a prescribed position by outputting different detecting signals from a sensor in accordance with positioning of the magnetic head on the 1st area including a track which is a border for a positioning reference and on the 2nd area excluding the track. CONSTITUTION:An outside direction signal ODR indicating the moving direction of a magnetic head 1 and a pulse signal STP for starting a moving operation are applied from an external controller 7 to a driving control circuit 4 in a floppy disk driver 1. An 'L' level signal when the head 3 is positioned in the area forming no track or an 'H' level signal when the head 3 is positioned in the area forming the track is applied from a sensor 8 in a head driving mechanism 6 to the circuit 4 as a detecting signal CTO. If the head 3 is positioned on the outside of the track area when power is ON, the head 3 is moved up to the area in the track based on the signal CTO, or when the head is positioned in the track area, the head 3 is moved up to the outside area of the track.
