致动器锁止设备和具有该致动器锁止设备的硬盘驱动器
摘要：
本发明提供一种致动器锁止设备和具有该致动器锁止设备的硬盘驱动器(HDD)。所述HDD包括：主轴电机；数据存储盘，安装在所述主轴电机上；致动器，使读/写磁头运动至所述数据存储盘之上的期望位置；致动器锁止设备，将所述致动器锁定在停放位置。所述致动器锁止设备包括：缺口，形成在摇臂的后端；锁止杆，与安装在基座上的枢轴结合并围绕该枢轴枢转。牵引构件安装在平衡块的上表面和下表面中的与磁体相邻的一个上，其中，所述平衡块形成在所述锁止杆的后端。当读/写磁头运转时，由于从所述磁体作用到所述牵引构件的磁力的竖直分力而使所述锁止杆与上磁轭或所述基座接触，从而限制所述锁止杆的竖直振动。
摘要（英）：

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.
