Magnetic disk device

Abstract

Abstract PURPOSE:To prevent the shaking of a disk device due to the reaction of a voice coil motor by arranging a head disk assembly (HDA) so that the head access direction of the HDA is made coincident with the direction of gravity. CONSTITUTION:Eight sets of the HDAs 2 are mounted to the upper stage of a frame 23 of a magnetic disk device so that the head access direction is the perpendicular direction as shown in the arrow 10. Further, a power supply 6 and a control circuit section 5 are mounted to the lower stage of the frame 3. When an information call instruction or a write instruction is given, a shock is caused in the access direction shown in the arrow 10, the shock is delivered from the HDAs 2 to the frame 3, a force moving vertically the entire frame 3, that is, the magnetic disk device is exerted and the vertical rigidity of the frame 3 is sufficiently high. Thus, the entire movement of the magnetic disk device is not almost caused.
