Abstract

A head support mechanism of the invention comprises a head (1011) for recording on a disk or reproducing a disk, a head support member composed of this head (1011) and a support arm (2) having this head (1011) attached to one end portion thereof, a base arm (12) including a rotation support part (11) for supporting the head support member rotatably in a vertical direction to the surface of the disk, and an elastic member (4) of which one end portion is connected to other end portion of the support arm (2) and other end portion is connected to the base arm (12) for thrusting the head support member in the disk direction. Therefore, the support arm (2) can be formed of a member of high rigidity, and the slider (1) is prevented from colliding against the disk if an impact force acts from outside.
