Abstract:
A magnetic head up/down mechanism for a magneto-optical disc drive, the magneto-optical disc drive recording/reproducing data on a magneto-optical disc, said mechanism being mounted on a carriage movable along a radial direction of said magneto-optical disc, said mechanism comprising:a magnetic head; a magnetic head supporting member mounting said magnetic head; an elongated plate spring member, said magnetic head supporting member being secured at an end portion in a longitudinal direction of said elongated plate spring member; and a moving system that moves said elongated plate spring member together with said magnetic head supporting member mounting said magnetic head to move between an operative position and a retracted position, said moving system being located on one side with respect to data recording surface of said magneto-optical disc, wherein said magnetic head is capable of applying magnetic field to said magneto-optical disc when said magnetic head is located at said operative position, wherein said magnetic head is retracted from said operative position and spaced from said magneto-optical disc when said magnetic head is located at said retracted position, and wherein said magnetic head is located on a data recording surface side of said magneto-optical disc at each of said operative position and said retracted position.
