Abstract:
1. An actuator latch apparatus for a data storage device comprising: a latch lever having a first latch portion at one end portion of the latch lever and having the other end portion fixed to a base plate of the data storage device, and made of a shape memory alloy capable of being deformed according to application of electric power; and a second latch portion provided at an end portion of an actuator moving a read/write head to a predetermined position of a disk, wherein, when the rotation of the disk is stopped and the actuator is parked at a parking position, the first latch portion of the latch lever interferes with the second latch portion, thus locking the actuator not to rotate, and when the disk rotates, the latch lever is deformed so that the first latch portion is separated from the second latch portion, thus allowing the actuator to rotate.
