摘要:
A hard disk balancing apparatus for a hard disk drive including an eccentricity detection unit to detect an eccentricity amount and an eccentricity position of the hard disk with respect to a rotation axis of a spindle motor for rotating the hard disk as an origin, and a pushing unit to push a circumference of the hard disk in the eccentricity position and to move the hard disk on the rotation axis of the spindle motor according to the eccentricity amount. Here, the eccentricity detection unit includes a detection sensor to detect the rotation axis of the spindle motor, and is placed coaxially with the rotation axis of the spindle motor, and at least three distance sensors that are separated from the detection sensor to be at least farther than a radius of the hard disk and to measure a distance between one point on the outer circumference of the hard disk and themselves.

An actuator latch apparatus of a hard disk drive for locking a pivoting actuator includes a locking protrusion provided at one side of the actuator, a latch lever pivotably installed on the base and elastically biased such that a hook portion provided at one side of the latch lever restricts the locking protrusion, and an air flow pipe provided at the base and generating a driving torque to the latch lever by a pressure differential between the atmosphere and air flowing along a channel formed in the air flow pipe. Thus, since locking and unlocking are performed by selectively restricting the locking protrusion provided at the actuator, unlocking can be smoothly performed without any impacts while a locking state is maintained firmly. Also, since locking and unlocking of the actuator is driven by elastic bias and the rotation of the hard disk, power consumption is reduced.

A disk drive having a base member, including: a printed circuit board installed on a rear surface of the base member, on which at least one chip is mounted; a first insulation panel arranged between the base member and the printed circuit board; at least one heat conductive plate arranged between the first insulation panel and the printed circuit board to absorb and transfer heat generated by the at least one chip; and a heat dissipative plate connected to the heat conductive plate and exposed to an outside of the disk drive to dissipate the heat transferred through the heat conductive plate.

A filtering apparatus of a hard disk drive includes a filter filtering particles from air flowing inside a housing which includes a base plate and a cover plate, and two holders installed inside the housing and having support grooves supporting both end portions of the filter. The filter includes a filtering portion through which the flowing air passes and particles are filtered from the flowing air, and an insertion portion included at both end portions of the filtering portion and inserted into the support grooves forming a seal. Thus, since no gap is generated between the support groove of the holder and the insertion portion of the filter, all the air flowing toward the filter passes through the filtering portion. Also, the flow of air passing through the filtering portion is smooth, so that an efficiency of filtering tiny particles included in the air flowing in the hard disk drive is improved.
摘要:
A spindle motor for a hard disc drive. The spindle motor includes an oil outflow prevention part mounted at an inner side of an oil inlet, preventing oil from flowing out through the oil inlet, but allowing an outflow of air bubbles that are generated due to gasification of the oil. Accordingly, the contamination of the spindle motor due to oil that has flowed out is decreased.

A hard disk drive having a disk storing data, a spindle motor rotating the disk, an actuator having two arms disposed at both sides of the disk, and a disk locking apparatus locking the disk not to rotate by closely contacting a side surface of the disk when the disk stops rotating. A suspension supporting a record/reproduce slider is installed at a first arm disposed at one side surface of the disk. The disk locking apparatus is installed at a second arm disposed at the other side surface of the disk. The disk locking apparatus has a dummy suspension whose one end portion is installed at the second arm and has a predetermined elastic force, and a dummy slider installed at other end portion of the dummy slider, and locking a stopped disk to prevent movement of the stopped disk and damage to bearings of the spindle motor.
