ABSTRACT:
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.
