    摘要: Described herein is a disk drive having a crash stop assembly that includes a crash stop section with an outer wall extending along a first axial length of the crash stop assembly and a retaining section extending from the crash stop portion. The retaining section includes a helical portion that is elastically compressible along a second axial length, different from the first axial length, of the crash stop assembly when a base and top cover of the disk drive are coupled together.

    摘要: The present invention may be regarded as a disk drive comprising a disk, an actuator arm comprising a head, and a voice coil motor for actuating the actuator arm to position the head radially over the disk. The voice coil motor comprises a first magnet for generating a first magnetic flux, and a rotary voice coil yoke comprising a magnetic flux conductor shaped to form an air gap with respect to the first magnet, the magnetic flux conductor comprising a first end having a first reluctance and a second end having a second reluctance, wherein the first reluctance is substantially lower than the second reluctance such that the magnetic flux conductor guides the first magnetic flux through the air gap and through the first end. A voice coil is wrapped around at least part of the magnetic flux conductor for conducting a current to generate a second magnetic flux such that at least part of the second magnetic flux is within the air gap for interacting with the first magnetic flux.
