摘要： A disk drive system and method for implementing the same. The disk drive system of the present invention includes a discoid medium which rotates about its rotation axis and stores data. An actuator includes a head for reading or writing data from or in the discoid medium as it bidirectionally rotates about its bidirectional-rotation axis. The disk drive system further includes a housing which has a predetermined width and houses the discoid medium and the actuator, wherein the rotation axis of the discoid medium and the bidirectional-rotation axis of the actuator are arranged at the center in the width direction of the housing, and wherein size of the discoid medium is smaller than that of a discoid medium corresponding to a form factor of the housing.

摘要： Embodiments of the invention establish electric continuity across an actuator head suspension assembly and a pivot bearing assembly without involving an increased manufacturing cost through a simple structure. In one embodiment, a carriage made of a plastic resin is provided with a pivot opening. A pivot bearing assembly is inserted into the pivot opening. The pivot opening includes a step formed by holes having different hole diameters from each other at an adjoining portion thereof. Two actuator arms are secured to the carriage through insert molding to support an HDA. One of the two actuator arms is provided with a hole functioning as a pivot opening and having a smaller hole diameter so as to form the step. The other of the two actuator arms is provided with a hole functioning as a pivot opening and having a larger hole diameter. The hole having the larger hole diameter includes protruded portions that abut against the pivot bearing assembly with no clearance therebetween. The hole also includes recessed portions disposed between each adjoining pair of the protruded portions and having a clearance from the pivot bearing assembly.

摘要： Embodiments of the invention permit a magnet-based actuator lock mechanism to operate smoothly in a magnetic disk drive that uses a base made of a magnetic material. In one embodiment, the base to be used is made of a magnetic material. The actuator lock mechanism includes a rotatable arm that retains a magnet. A magnetic attraction force, which is oriented toward the base as indicated by an arrow, is generated in the magnet. The base is provided with a cut to reduce the attraction force. The cut is covered with a sealing material to maintain internal airtightness. The actuator lock mechanism may be, for instance, an eddy-current latch, inertia latch, or magnetic latch.

摘要： Embodiments of the invention provide an actuator head suspension assembly having an efficient voice coil. In one embodiment, a voice coil is formed in a circular or any other shape than the conventional sectorial shape to increase the efficiency of the voice coil and diminish oscillation and noise of an actuator head suspension assembly. The voice coil shape is selected such that the proportion of an out-of-plane force becomes smaller than that in the conventional sectorial voice coil and the proportion contributing as weight to the oscillation energy also becomes smaller.

摘要： Embodiments of the invention provide a rotary disk storage device in which dust particles are less likely to deposit on the air bearing surface of each head/slider. The actuator head suspension assembly is configured so as to make the skew angle of the head/slider positive at about 80% or more of all the tracks. Specifically, the actuator head suspension assembly is configured in such a manner that the distance L2 between the center of the pivot shaft and the intersection point P of the trailing edge of the head/slider is made longer than a given length or there is an angle β between the reference line Y and the pivot line Z.

摘要： A head stack assembly for a hard disk drive has an actuator comb body, a coil yoke, at least one actuator arm, and a prosthesis. The prosthesis is an artificial or replacement arm and is preferably identical in profile and thickness as the actuator arm, except for some or all of the balance holes in the actuator arm. This configuration eliminates the need to provide the prosthesis with a real or dummy head in order to balance the actuator, thereby reducing cost. A common stamping die and a common molding die are used for both the arm and the prosthesis, which further reduces the cost of manufacturing.

摘要： Terminals of a flexible printed circuit board and terminals of a wiring trace in a head suspension assembly are to be connected with each other by soldering without causing a soldering defect. In an embodiment, a terminal structure of a multi-connector in a wiring trace which includes an insulating layer and a conductor pattern portion formed on a surface of the insulating layer is provided with exposed portions of terminals exposed from apertures formed in part of the insulating layer and is also provided with lining portions adjacent to the exposed portions in a longitudinal direction of the conductor pattern portion and bonded to the insulating layer. Even if terminals of the multi-connector are cracked when soldered, not only conductivity is ensured, but also it is possible to strengthen the terminals, because the lining portions of the terminals are bonded to the insulating layer.
