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.

1. Field of the Invention
The present invention relates to an actuator latch apparatus of a hard disk drive for locking or unlocking an actuator of a hard disk drive.
These and/or other aspects and advantages of the invention will become apparent and more readily appreciated from the following description of the preferred embodiments, taken in conjunction with the accompanying drawings of which:
FIG. 1 is a plan view showing a hard disk drive having a conventional actuator latch apparatus;
FIG. 2 is a perspective view illustrating a hard disk drive having an actuator latch apparatus according to a first embodiment of the present invention;
Reference will now be made in detail to the present preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
Referring to FIG. 2, a hard disk drive includes a hard disk 200 installed on a base 100 to be capable of rotating and a magnetic head transfer apparatus for transferring a magnetic head 500 for recording and reproducing information to and from a desired track position on the hard disk 200.
The magnetic head transfer apparatus includes an actuator 300 installed on the base 100 to be capable of pivoting and where the magnetic head 500 is installed at one side thereof, a voice coil motor (not shown) pivoting the actuator 300 to move the magnetic head 500 across a parking area 210 and a record area 220 formed on the hard disk 200, and a latch apparatus locking the actuator 300 after the magnetic head 500 is disposed in the parking area 210 of the hard disk 200.
