Abstract
PURPOSE:To prevent a harmful influence upon a recording signal because of being out of a track area even when a flaw should arise on a magnetic disk by positioning a magnetic head out of the track area at the time of non-rotation. CONSTITUTION:When a magnetic disk back is mounted, a system computer 10 will be operated, so that the magnetic head 20 will be transferred up to contact with a non-recording track. Then, when a shutter button is not operated, the magnetic head 20 will be transferred out of the track area S. When the shutter button is half pressed, a position of the read prior to its transfer will be read out of a memory 30, so as to bring the magnetic head 20 back into its original position (abutting position on the non-recording track). Then, after recording by pressing the shutter, the magnetic head 20 will be transferred by two tracks. Afterward, when the shutter is not operated even after a lapse of a period of waiting time (w), the magnetic head 20 will be transferred out of the track area, and then an electric power source circuit will be off. By this method, at the time of starting, the magnetic head will be positioned out of the track area, so that even when a flaw should arises on a disk, any lack of the signal would never be generated due to the outside of the track area.
