IPC: G11B5/48
Filed: 1983-10-12
Abstract: PURPOSE:To prevent a magnetic head from wearing by arranging a magnetic head opposite to a stabilizing plate across a discoid recording medium, providing a movable body at the circumference of this magnetic head, and moving forth this movable body from the tip of the magnetic head toward the disk when neither recording nor reproduction is performed. CONSTITUTION:A solenoid 20 is powered off in a stand-by state and the movable body 12 is energized with the tensile force of a tension spring 16 to rotate until it contacts a stopper 17. Consequently, the tip part of the movable body 12 moves forth slightly from the tip part of the magnetic head 11 toward the disk. Therefore, the disk 1 and magnetic head 11 do not contact each other. The projection part 23 of the movable body 12 contacts the disk 1 instead, so the disk 1 is put between the stabilizing plate 22 and the projection part 23 of the movable body 12 and continues to rotate stably. Thus, the wear of the head 11 is eliminated. Further, the disk 1 never vibrates abnormally.
