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.

    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 in accordance with the present invention relate to suppressing deterioration in rigidity and dynamic characteristics of a tab even when an initial point of contact between a tab and a ramp during unloading is set closer to the outer periphery of a disk. A data storage device in one embodiment of the present invention includes a head, a ramp for unloading the head, a load beam having a head support portion for supporting the head and a tab adapted to slide on a sliding surface of the ramp on a front end side with respect to the head support portion, and an actuator having the load beam and adapted to actuate the head for loading and unloading. During unloading, a portion of the tab offset from the center in the transverse direction of the tab first comes into contact with the sliding surface of the ramp. The load beam has a flange formed to be bent and continuously from the front end portion of the tab up to both ends of the head support portion.
