Magneto-optic disk device and method of positioning magnetic head of the device

A method of adjusting the position of a magnetic head of an optomagnetic disk device wherein a head support unit (20) comprises a pickup (12) having an objective lens (10) mounted thereon for converging a laser beam, and a head arm (14) having one end attached to the pickup (12) and a free end provided with the magnetic head (16), the head arm (14) being positionable relative to the pickup (12) so that the magnetic head (16) is opposed to the objective lens (10) on the pickup (12), the head support unit (20) being movable radially of an optomagnetic disk,

• the method being characterized by adjusting the position of the magnetic head of the optomagnetic disk device comprising the pickup (12) having at least one screw hole (22) for mounting the head arm (14), the head arm (14) having a slit (24) opposed to the screw hole (22) of the pickup (12) and in parallel to a tangential direction of the disk, the screw hole (22) of the pickup (12) and the slit (24) of the head arm (14) being provided with a screw (26) slidably fitting in the slit (24) and having a distal end screwed in the screw hole (22), and the screw (26) being provided at a base end thereof with an elastic member (30) for pressing the head arm (14) against the pickup (12),
• the method comprising moving the head arm (14) relative to the pickup (12) tangentially of the disk, with the head arm (14) pressed against the pickup (12) by the elastic member (30), to adjust the position of the magnetic head (16) relative to the objective lens (10) on the pickup (12) and thereafter fixing the head arm (14) to the pickup (12).
