A magnetic head mechanism includes head support bases which are provided on a head carriage and a head arm. The head support base is formed to support a magnetic head at a position within a disk case. The magnetic heads are supported in a state raised from the head carriage and the head arm by the head support bases which are resilient. A wall and a frame shaped part of the head support part are provided so as to enter within the disk case via corresponding one of openings in the disk case. For this reason, even when the magnetic disk rotates at a high speed, the magnetic heads can follow the magnetic disk by stably swaying, so that a sufficient head touch of head pressure is secured.
