Abstract
A magnetic head up/down mechanism for an magneto-optical disc drive is provided with a magnetic head supporting member mounting a magnetic head. The supporting member is attached to one end of an elongated plate spring member. A moving system is further provided to move the plate spring member together with the supporting member so that the magnetic head is located either an operative position or a retracted position. The operative position and the retracted position are located between an objective lens of the disc drive and the data recording surface of a magneto-optical disc loaded in the magneto-optical disc drive.
