    摘要: The present invention relates to a low cost voice coil motor for use in a disc drive. In accordance with one embodiment of the invention, the voice coil motor includes at least one overmold encapsulating an assembly of a magnet and a pole. The overmold thus provides a barrier against outgassing and corrosion.

    摘要: Disc drives are made with an actuator designed with at least one asymmetrical arm having two masses that move out of phase. The arm is modified by removing a portion of the higher-energy (longitudinal) side, the one with the greater total time-averaged strain energy. This modification reduces the phase difference between the first and the second arm, particularly for a relevant frequency range of interest. Disc drives made by this method exhibit a generally reduced out-of-phase motion, enhancing performance during seeking and track following, especially for arms with two heads that interact with surfaces of opposing discs.

    摘要: An actuator assembly of a disc drive having an actuator arm rotatably mounted adjacent a data disc. The actuator arm has a top surface and a bottom surface, and includes a head gimbal assembly support portion located at one end of the actuator arm. The actuator assembly further includes an arm circuit fastened to the top surface of the actuator arm. The actuator assembly may additionally include a head gimbal assembly that electrically couples the data transducer and the arm circuit. The gimbal circuit is partially routed along the head gimbal assembly and over the top surface of the actuator arm. Alignment apertures on the arm circuit and the head gimbal circuit and alignment pins on the actuator arm may be used for positioning of the circuits over the top surface of the actuator arm.
