PURPOSE:To reduce track deviation caused by disk flexure by supporting tiltably a first magnetic head in the tangential direction of the track by a spring sheet having a pair of connecting parts, and supporting tiltably a second magnetic head in the radial direction of the disk and in the direction perpendicular thereto by a spring sheet having two pairs of connecting parts. CONSTITUTION:The first magnetic head 54 is supported for vertical movement and turnably in the radial direction 80 to be used as axis by a spring sheet 57 having a pair of connecting parts 78, 79 provided along the radial direction. The second magnetic head 55 is supported turnably in the radial direction and the perpendicular direction thereto by a spring sheet 62 having two pairs of connecting parts 86, 87 and 90, 97 provided along the radial direction 85 and the direction 89 perpendicular thereto. When the disk 18 is flexed in the rotational direction, the head 55 supported by gimbals to follow up with it is tilted slightly. However, the head 54 supported by the connecting parts 78, 79 is hardly tilted so that fluctuation in a gap distance L between cores 81, 93 are minimized to reduce tracking deviation.
