发明名称 Magnetooptical recording apparatus having retreatable magnetic head
摘要 There is provided a magnetooptical recording apparatus which records information by applying a magnetic field for recording from a magnetic head while irradiating an light beam onto a magnetooptical disk from an optical pickup, the apparatus comprising an optical pickup, a magnetic head having a slider that moves in a radial direction of a magnetooptical disk together with the optical pickup and is abutted against a recording surface of the magnetooptical disk and first and second elastic members that support the magnetic head, wherein a base end portion of the first elastic member is fixed to a given position of a substrate that supports the magnetic head, the second elastic member is folded with respect to the first elastic member, and a base end portion of the second elastic member is fixed to the slider, and a displacement of the magnetic head in the tangential direction due to vertical displacement of the magnetooptical disk is canceled by displacements which are respectively caused by the first and second elastic members and act in mutually opposite directions, whereby the displacement of the magnetic head in the tangential direction can be suppressed and the apparatus can be reduced in size.
