ABSTRACT:
A mechanism for lifting and lowering a magnetic head into and out of contact with a magnetic medium such as a magnetic sheet includes at least one guide shaft rotatably supported on a frame and having an eccentric portion. A magnetic head carriage supports a magnetic head thereon and is slidably movable along the guide shaft toward a recording/playback position, the magnetic head carriage having an end held in engagement with the eccentric portion of the guide shaft. A driver mechanism is mounted on the frame for rotating the guide shaft to cause the eccentric portion to displace the magnetic head toward a backing plate with a magnetic medium such as a magnetic sheet interposed therebetween.
