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： Embodiments in accordance with the present invention provide achieve an increase of storage capacity and thinning down of a disk drive by reducing effects from an error in an assembly position of a ramp. A data storage device according to an embodiment of the present invention includes a head, a ramp, a load beam, and an actuator. The ramp includes a portion onto which the head is retracted from a surface of a medium. The load beam includes a head support portion that supports the head and a tab disposed more on the side of a leading end than the head support portion. The tab has a leading end that slides over, while being in contact with, a sliding surface of the ramp. The actuator includes the load beam and loads and unloads the head.

摘要： Embodiments of the invention reduce the height of a ramp to provide a thin data storage device that is capable of inhibiting the deterioration of the dynamic characteristics at the time of loading/unloading. In one embodiment, a data storage device includes a head that accesses a recording region of a recording disk; a ramp that is positioned circumferentially apart from an outermost end of the recording disk to unload the head from a surface of the recording disk; and an actuator that includes a load beam for supporting the head and moves the head. The load beam includes a tab that is extended from a leading end section of the load beam, beyond the head support section of the load beam, and toward the recording disk, and slides over a ramp surface.

摘要： A voice-coil motor (VCM) with voice coils configured to reduce vibrations of a head when data is accessed on a disk in a disk drive. The VCM includes at least one VCM magnet and a voice-coil assembly. The voice-coil assembly includes a first voice coil and at least a second voice coil. The first voice coil is disposed in proximity to a magnetic pole of the at least one voice-coil-motor magnet. The second voice coil is disposed in close proximity to the first voice coil such that the first voice coil substantially overlays the second voice coil. The first voice coil and the second voice coil are configured to reduce vibrations of the head when data is accessed on a disk in the disk drive. A rotary actuator including the voice coils and a disk drive including the VCM are also provided.
