A magnetic disk chucking mechanism comprises a disk table (21) having an aperture (21a) formed at a position apart from the center of the disk table (21), an arm (22) attached to the lower surface of the disk table, and a roller 23 held by the arm and protruding from the upper surface of the disk table (21) through the aperture (21a). The arm (22) has elasticity and is directly fixed to the disk table (21) at least at one position apart from the roller (23). The roller (23) is held by the arm (22) to be movable within the aperture (21a) at least in a radial direction of the disk table (21).

A flexible printed wiring board (29-1) is brought into contact with an insulating tape (31-1) attached onto an internal wall of an upper case (30) with the movement of a head carriage (25). The flexible printed wiring board (29-1) is coated with an antistatic agent (50) to prevent occurrence of static electricity resulting from frictional contact between the flexible printed wiring board (29-1) and the insulating tape (31-1).
