摘要： A suspension clamp is disclosed for clamping a disk drive suspension to an actuator arm. The suspension clamp comprises a housing including a spring operable to bias a latching member, wherein the latching member is rotatable about a pivot. After compressing the spring and rotating the latching member in a first direction, the latching member is operable to clamp the suspension to the actuator arm by decompressing the spring.

摘要： A disk drive is disclosed comprising an actuator arm, a head coupled to the actuator arm, and a voice coil motor for actuating the actuator arm to move the head. The voice coil motor comprises a first magnet for generating a first magnetic flux, and a yoke comprising a magnetic flux conductor for guiding the first magnetic flux. The magnetic flux conductor comprises a body and a top and bottom protruding plate portions, wherein the body and the plate portions are integrally formed. The body defines, in vertical cross section, a primary bend having a primary bend radius and at least one secondary bend having a secondary bend radius.

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.
