Abstract
A cover structure of a hard disk drive (HDD) can optimally suppress noises and vibrations generated in the HDD. The hard disk drive includes a cover, a cover damper mounted on the cover, and an air layer provided between the cover and the cover damper.
Claims36
A cover structure of a hard disk drive, comprising:
- a cover;
- a cover damper mounted on the cover;
- and
- at least one recess formed in the cover, at least one air layer being formed between the cover and the cover damper when the cover damper is mounted on the cover to at least partly enclose the at least one air layer within the at least one recess, the at least one recess being formed to prevent air from passing from an exterior of the hard disk drive to an interior of the hard disk drive directly through the at least one recess, the at least one air layer not encircling a rotation axis of an actuator of the hard disk drive.

A cover structure of a hard disk drive, comprising:
- a cover having a stepped surface formed at an upper portion thereof and at a portion being apart from a rotation axis of an actuator;
- a cover damper;
- and
- at least one air layer formed between the cover and the cover damper, the at least one air layer being formed to prevent air from passing from an exterior of the hard disk drive to an interior of the hard disk drive directly through the at least one air layer, the at least one air layer not encircling the rotation axis of an actuator of the hard disk.
1 more element
A hard disk drive, comprising:
- a rectangular base;
- a spindle motor mounted in the base, and having a rotation axis perpendicular to the base;
- a hard disk mounted to the spindle motor;
- an actuator mounted on the base, said actuator having a second rotation axis perpendicular to the base;
- a flexible printed circuit connected to the actuator and located on one side of the rotation axis of the actuator;
- a cover formed of a first material mounted on the base, said cover comprising:
- a top cover substantially parallel to said rectangular base;
- at least one recess formed on one portion of the top surface, said at least one recess being formed spaced apart from said rotation axis of said spindle motor and spaced apart from said second rotation axis of said actuator;
- and
- a damper formed of a second material mounted on the top surface of said cover, enclosing an air gap between the damper and the at least one recess of the top surface, the at least one recess being formed to not allow air to directly pass from an exterior of the hard disk drive to an interior of the hard disk drive through the at least one recess, the air gas not encircling the second rotation axis of the actuator of the hard disk.
