    摘要: A unitary load beam for a disk drive suspension in which the radius of the perimeter transition between the load beam portion and the load beam spring portion is increased to ensure the stress encountered when the load beam is bent from its normal range, for installation into a disk drive, for example, from a previously typical 0.002 inch to 0.010 inch, is distributed sufficiently that the load beam spring portion is subject to only elastic, not plastic deformation. Thus, the gram loads exerted by the load beam spring portion are reliably consistent.

    摘要: An actuator arm design having a close cross section which greatly improves the performance of the disc drive. The actuator arm is formed of a top skin, a bottom skin, and a core. The core may be formed of a corrugated metal, or a foam metal, or a combination of the two. As a result of this structure of the arm, the arm is highly stiff, yet low mass which yields an arm having a high resonant frequency.

    摘要: A flex circuit for use in a head gimbal assembly having additional polyamide features which improve the damping properties of the flex circuit. An elbow or damping strips with or without metal traces can be added to the flex circuit to dampen the first torsion gain. The elbow or damping strips with or without metal traces do not act as a substrate for electrical circuitry, but rather provide damping properties to the head gimbal assembly.

    摘要: A suspension load beam for an actuator assembly of a disk drive includes a bend radius portion with a spring rate that is less than 18 Newtons per meter, a first bending mode that is greater than 3,500 Hertz, and a first torsion mode that is greater than 5,300 Hertz. The method of making this suspension load beam includes cutting a sheet of material to form a flat suspension load beam including a bend radius portion, removing material in the bend radius portion from full thickness, inspecting the bend radius portion to determine its thickness, and removing material from the bend radius portion and/or from the main body of the suspension load beam to compromise the performance difference due to thickness variation in bend radius portion.

    摘要: An actuator arm assembly for a disk drive is disclosed. The actuator arm assembly includes at least two actuator arms, each having a corresponding suspension and read/write head. A one-piece flex cable is attached to the upper or lower surface of each of these actuator arms, and includes at least one preamp. The flex cable provides an electrical interconnection between the read/write heads of these two actuator arms and a drive electronics board. Both of these actuator arms may be detachably interconnected with a spacer via at least one snap-lock type interconnection to allow for a “no tools” assembly/disassembly of the actuator arm assembly.

    摘要: An apparatus with ring shape sleeve is provided. The apparatus is attached to a shaft and moves around the shaft, the varieties of the apparatus comprise objective lens holder of pick-up head. The characteristic of the invention is that apparatus and shaft are attached by ring shape sleeves where not only thickness of any ring shape sleeve is thin enough such that draft angle effect is negligible but also ring shape sleeve can be inlayed in the apparatus or be molded integrally with the apparatus. Therefore, not only shaft and apparatus are rigorously attached but also the space between shaft and apparatus is significant decreased. Thus, dynamic behavior of the apparatus is more controllable and yield of the apparatus is improved.

    摘要: There is disclosed a disc drive suspension in which a first reference hole and spring portion, and a second reference hole and spring portion are formed in a load beam of the suspension. A third reference hole and spring portion, and a fourth reference hole and spring portion are formed in a flexure. When a first positioning pin of a positioning jig is inserted into the first and third reference holes, the first and third spring portions abut on the first positioning pin, and the load beam and flexure are thereby urged in an axial direction. When a second positioning pin is inserted into the second and fourth reference holes, the second and fourth spring portions abut on the second positioning pin, and the load beam and flexure are thereby urged in the axial direction, and are both positioned.

    摘要: A magnetic coil actuator which can provide a higher output but maintains the original volume and the same power consumption is disclosed. The coil actuator uses a movable magnetic coil which is adjusted of its shape to meet the magnetic field of a static magnet. The coil is suitably bent to have its two diametric sections falling into the magnetic lines of the magnet, so as to maximize the usage rate of the coil to the magnetic field. Therefore, the coil actuator provides a higher output applicable to a tracking or focusing device of a pickup head, and meets the requirements of high speed optical recording devices.
