ABSTRACT:
A magnetic head device for magneto-optical recording, employed for magneto-optical disc recording/reproducing apparatus, includes a magnetic head element, a slide contact member carrying the magnetic head element and having a slide contact portion having a sliding contact with a magneto-optical disc and a head support supported for rotation on a stationary portion of a movable base supported for movement radially of the magneto-optical disc via first resilient flexible portions and supporting the slide contact member for rotation at its distal end via second resilient flexible portions. A weight mass is formed integrally with the head support closer to the stationary portion than the first resilient flexible portions.
