Abstract
Provided are an actuator latch apparatus and a hard disk drive (HDD) having the actuator latch apparatus. The HDD includes a spindle motor, a data storage disk which is installed on the spindle motor, an actuator which moves a read/write head to a desired position above the data storage disk, and the actuator latch apparatus which locks the actuator in a parking position. The actuator latch apparatus includes a notch which is formed at a rear end of a swing arm and a latch lever which is combined with and pivots on a pivot shaft installed on a base. A retractor member is installed on one of upper and lower surfaces of a counterbalance which is adjacent to a magnet, wherein the counterbalance is formed at a rear end of the latch lever. When the read/write head operates, the latch lever contacts an upper yoke or the base due to a vertical component force of a magnetic force working from the magnet to the retractor member, thereby liming a vertical vibration of the latch lever.
