Abstract
A disk drive includes a head carriage movable in a radial direction of a disk mounted on the disk drive, a guide rod fixed on a frame of th disk drive for guiding the head carriage, a voice coil motor including a magnetic circuit screwed on the frame and a drive coil mounted on the head carriage, a guide-rod catching member provided on the frame so as to catch the guide rod, and a resilient guide-rod urging member resiliently urging the guide rod against the guide-rod catching member, wherein the resilient guide-rod urging member is screwed on the frame together with the magnetic circuit.
Claims5
A disk drive, comprising:
- a frame;
- a rotatable turntable adapted to support a disk;
- a head carriage movable in a radial direction of said disk in a state that said disk is held on said turntable;
- a head provided on said head carriage, said head conducting writing or reading of information to and from said disk;
- a guide rod fixed on said frame so as to guide said head carriage;
- a voice coil motor including a magnetic circuit screwed on said frame and a drive coil mounted on said head carriage, said voice coil motor causing said head carriage to move in said radial direction of said disk;
- a guide-rod catching member provided on said frame so as to catch said guide rod;
- and
- a resilient guide-rod urging member screwed on said frame together with said magnetic circuit, such that said guide-rod urging member resiliently urging said guide rod against said guide-rod catching member.
