Method for aligning actuator assembly to a base in a miniature optical disk drive

摘要

Disclosed is a method for aligning a rotating device such as an actuator assembly to a base of, for example, a disk drive. The device is rotatably mounted to the base about the pivot pin. The method may involve adjusting the angular position of the pivot pin relative to the base unless or until the actuator assembly rotates in a first plane parallel to a second plane containing a surface of the data storage disk. In one embodiment, the data storage disk is mounted for rotation on a disk rotation motor. The disk rotation motor, in turn, is mounted to a base. With the device positioned between the base and the data storage disk, the device is rotated about the pivot pin. While the device is rotated about the pivot pin, electrical current is provided to the device. The magnitude of the electrical current is proportional or inversely proportional to a distance D separating the device from the data storage disk. The electrical current is monitored as the device rotates about the pivot pin. When the monitored current is constant in magnitude as the device rotates about the pivot pin, the angle between the device and the base is such that the device should rotate in the first plane.
