ABSTRACT:
A magnetic head drive mechanism in a photo-electro-magnetic disk drive is so designed that a magnetic head is coupled to the end portion of a swingable arm, and, as a photo-electro-magnetic disk is loaded or unloaded, the arm is swung, to move the magnetic head towards or away from the surface of the photo-electro-magnetic disk. In the magnetic head drive mechanism, pins are provided on both sides of the magnetic head, respectively, and a first engaging groove which is engaged with the pin and a second engaging groove which is engaged with the pin are provided on both sides of the opening of a cartridge head, respectively, whereby, at the unloading time both sides of the magnetic head are locked; that is, the vibration of the magnetic head is prevented during the transportation.
