    • 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.
    • 提供了具有致动器锁定装置的致动器锁定装置和硬盘驱动器(HDD)。 HDD包括主轴电动机,安装在主轴电动机上的数据存储盘,将读/写头移动到数据存储盘上方的期望位置的致动器,以及将致动器锁定在停车中的致动器闩锁装置 位置。 致动器闩锁装置包括形成在摆臂的后端处的凹口和与安装在基座上的枢轴上组合并且枢转的闩锁杆。 牵开构件安装在与磁体相邻的平衡体的上表面和下表面中的一个上,其中所述平衡物形成在所述闩锁杆的后端。 当读/写头操作时,由于从磁体作用到牵开器构件的磁力的垂直分力,闩锁杆接触上磁轭或底座,从而使闩锁杆的垂直振动降低。
