摘要： 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.

摘要： 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.
