ABSTRACT:
An actuator latch apparatus for a data storage device includes a latch lever installed on a base plate of the data storage device capable of pivoting and having a first latch portion provided at one end portion of the latch lever, a spring connected to the other end portion of the latch lever and made of a shape memory alloy to allow the latch lever to pivot in a predetermined direction by 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. When the rotation of the disk is stopped and the actuator is parked at a parking position, the spring allows the latch lever to pivot in one direction so that the first latch portion interferes with the second latch portion, thus locking the actuator not to rotate, and when the disk rotates, the spring allows the latch lever to pivot in the opposite direction so that the first latch portion is separated from the second latch portion, thus allowing the actuator to rotate. Thus, a reliable operation of the actuator latch apparatus is available due to the characteristic of the shape memory alloy and the structure of the actuator latch apparatus is simplified.
