摘要： Embodiments in accordance with the present invention reduce the height of a head gimbal assembly (HGA) while maintaining the rigidity of a load beam. According to one embodiment of the present invention, an HGA includes a slider, a flexure, and a load beam. The load beam includes a flange formed to protrude to the opposite side to a magnetic disk at the edge of the load beam extending in the length-wise direction. The load beam has a recessed portion opened to the side opposing the magnetic disk and having an opening area larger than the area of the back surface of the slider opposing the flexure. The slider is provided in the recessed portion so that the position of the surface of the load beam is between a virtual surface including the surface of the slider opposing the magnetic disk and a virtual surface including the slider back surface.

摘要： The present invention provides a depopulation version hard disk drive apparatus that has a reduced number of magnetic heads and suspension arms from a standard hard disk drive apparatus, wherein the magnetic head can still be properly controlled during a loading state. The hard disk drive apparatus includes a ramp which interfaces with the suspension arm when loading and unloading the arm. An angle of a second slope surface 61c of the ramp in the depopulation version hard disk drive is set larger than that of the corresponding slope surface of the ramp 6 the a standard version hard disk drive.

摘要： A magnetic circuit is provided in an enclosure that can efficiently generate magnetic flux from the enclosure, configuring a magnetic disk, to a magnetic disk. Thus, by providing such a magnetic circuit, a magnetic field different from that in other enclosure parts, that is, a local magnetic field, is generated from the magnetic circuit in case the disk device is set in an external magnetic field. Hence, this local magnetic field can effectively erase data in the magnetic disk. In particular, since the local magnetic field is generated even if the external magnetic field is weak, it is possible to not only suppress the demagnetization of permanent magnets used in the spindle motor at minimum, but also effectively erase data in the magnetic disk.

摘要： Embodiments of the invention provide a support structure for a voice coil that is not easily damaged even when a carriage assembly used in a magnetic disk drive is made thinner. In one embodiment, the voice coil includes a stack of a plurality of layers of aligned windings held between an outer holding portion and an inner holding portion of the carriage assembly. The carriage assembly is formed integrally with the voice coil through injection molding. An outermost peripheral layer is a conductive wire wound a number of turns that falls short of the number of turns required to constitute a complete layer. A step is thereby formed between the outermost peripheral layer and a layer adjacent thereto and inner therefrom. The outer holding portion includes a reinforcement portion formed thereon to cover part of a transverse end face of the voice coil. The outermost peripheral layer opposes a force acting on the outer holding portion from top downward and the reinforcement portion opposes a force acting on the outer holding portion from bottom upward.
