Claims
- 1. A disc drive having a base, a cover, and a spindle motor mounted on the base that is operable to spin a disc, the disc drive comprising:
an actuator assembly mounted on the base operable to move a transducer head over a data surface of the disc; a voice coil motor operable to rotate the actuator assembly, the voice coil motor including a bottom pole adjacent the base, an opposing top pole adjacent the cover forming a gap between the poles, and a coil mounted on the actuator assembly in the gap between the top and bottom poles; a flexible cable coupled to the head having first and second ends and a middle section extending between the first and second ends, wherein the first end is secured to the actuator assembly; and a flex clamp fastened to the base and securing the second end of the flexible cable to the base, wherein the flex clamp comprises a body and a clamp arm extending from the body, the clamp arm extending over the bottom pole of the voice coil motor and retaining the bottom pole between the clamp arm and the base.
- 2. The disc drive of claim 1, wherein the flex, clamp comprises a unitary member including the body and the clamp arm.
- 3. The disc drive of claim 1, wherein the bottom pole has one end that is secured to the base by a fastener and another end that is retained on the base by the clamp arm.
- 4. The disc drive of claim 1, wherein the top cover clamps the bottom plate to the base when the top cover is fastened to the base.
- 5. The disc drive of claim 1, wherein the flex clamp includes a pair of walls joined by a bridge to form a channel between the walls, the channel receiving a portion of the flexible cable.
- 6. The disc drive of claim 5, wherein clamp arm extends from one of the walls.
- 7. The disc drive of claim 6, wherein flex clamp further comprises a support arm extending from the body of the flex clamp, the support arm supporting the middle section of the flexible cable as the middle section extends from the flex clamp toward the actuator assembly.
- 8. The disc drive of claim 7, wherein the support arm and the body of the flex clamp form a channel and a bottom edge of the flexible cable is seated in the channel.
- 9. The disc drive of claim 7, wherein the support arm inhibits sagging of the middle section of the flexible cable.
- 10. The disc drive of claim 1, wherein the flex clamp comprises a polymer material.
- 11. In a disc drive having a base, a cover, a spindle motor mounted on the base that is operable to spin a disc, an actuator assembly mounted on the base that is operable to move a transducer head over a data surface of the disc, a voice coil motor operable to rotate the actuator assembly, the voice coil motor having top and bottom magnetic poles and a coil mounted on the actuator assembly between the top and bottom poles, and a flexible cable coupled to the head having first and second ends and a middle section extending between the first and second ends, wherein the first end is secured to the actuator assembly, a flex clamp fastened to the base and securing the second end of the flexible cable to the base, the flex clamp comprising:
a body; a clamp arm extending from the body and over a portion of the bottom pole, the clamp arm retaining the portion of the bottom pole between the clamp arm and the base; and a support arm extending from a body of the flex clamp, the support arm supporting the middle section of the flexible cable as the middle section extends from the flex clamp.
- 12. The flex clamp of claim 11, wherein the body, the clamp arm, and the support arm form a unitary member.
- 13. The flex clamp of claim 11, wherein the bottom pole has one end that is secured to the base by a fastener and another end that is clamped to the base by the clamp arm.
- 14. The flex clamp of claim 11, wherein the top cover clamps the bottom plate to the base when the top cover is fastened to the base.
- 15. The flex clamp of claim 14, wherein the flex clamp further comprises a pair of walls joined by a bridge to form a channel between the walls, the channel receiving a portion of the flexible cable.
- 16. The flex clamp of claim 15, wherein clamp arm extends from one of the walls.
- 17. The flex clamp of claim 11, wherein the support arm and the body of the flex clamp form a channel and a bottom edge of the flexible cable is seated in the channel so that the support arm inhibits sagging of the middle section of the flexible cable.
- 18. The flex clamp of claim 11, wherein the flex clamp comprises a polymer material.
- 19. A disc drive having a base, a cover, a spindle motor mounted on the base that is operable to spin a disc, an actuator assembly mounted on the base that is operable to move a head over a data surface of the disc, a voice coil motor operable to rotate the actuator assembly, the voice coil motor having bottom and top magnetic poles forming a gap between the poles, and a coil mounted on the actuator assembly in the gap between the top and bottom poles, the disc drive comprising:
a flexible cable coupled to the head having first and second ends and a middle section extending between the first and second ends, wherein the first end is secured to the actuator assembly; and means for securing the second end of the flexible cable to the base and for retaining the bottom pole between a clamp arm and the base.
- 20. The disc drive of claim 19, wherein the means for securing and clamping comprises a flex clamp secured to the base.
- 21. The disc drive of claim 20, wherein the flex clamp comprises a body, and the clamp arm and the body are both part of a unitary member.
- 22. The disc drive of claim 19, wherein the means for securing and clamping further comprises means for supporting the middle section of the flexible cable.
- 23. The disc drive of claim 22, wherein the means for securing, clamping, and supporting comprises a flex clamp secured to the base, the flex clamp comprising a support arm extending from a body of the flex clamp, the support arm supporting the middle section of the flexible cable as the middle section extends from the flex clamp toward the actuator assembly.
