    摘要: A system for controlling a distance between an optical head and the surface of a rotating optical disk comprising: an actuator arm having a first and second surface, the first surface facing the optical disk, the second surface facing away from the optical disk; an electromagnetic coil having an inner void, said coil adjacent to the second surface of the arm; and at least one permanent magnet producing a magnetic field that passes through the coil such that when an electric current is applied to the coil, a force is created at two or more segments of the coil.

    摘要: An optical assembly including a service loop extended from a focus section of an actuator arm. A portion of the service loop bends when a tracking section of the actuator arm rotates around a tracking axis while a portion of the flex circuit twists when the focus section of the actuator arm rotates around a focus axis.

    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.
