    摘要: A disk drive has at least one disk for storing data and at least one transducer for reading or writing data to or from the disk. The transducer is attached to an actuator which positions the transducer with respect to the disk. The actuator includes a controllable motor which is used to move the actuator and the transducer attached thereto. The disk drive also includes a ramp for off loading the transducer or for parking the transducer off of the surface of the disk. The disk drive includes a combination shock absorber and gasket that has locking tabs to keep the combination shock absorber and gasket in place during a shock or impact loading event. The combination shock absorber and gasket also can be provided with additional extensions to lessen shocks caused by flat drops. Elastomeric blocks or pads can be provided on the cover and the base to lessen shocks caused by flat drops. The drive can also have rotatable elastomeric blocks that can rotate to a position above the disk drive to lessen shocks resulting from flat drops. The drive also is provided with a shock sensor which provides visual evidence that the drive has undergone a shock of a predetermined threshold. Another shock absorbing system uses a shroud around the connector on the disk drive.

    摘要: A slider assembly for an optical disc drive includes a flyable slider supporting a pad with a pair of piezoelectric beams mounted to the pad to extend in spaced relation over the slider. An objective lens is mounted to the beams as to be cantilevered over the slider body. The beams are operable to deflect along the yawl axis of the slider to thereby move the objective lens and alter the position of the focal point. When operated independently, the beams rotate the objective lens about the roll axis of the slider to alter the radial position of the focal point. When operated together, the beams move the objective lens to focus the focal point relative to the recording medium. The beams are optionally operable to deflect along the pitch axis of the slider to thereby radially move the objective lens and alter the position of the focal point.

    摘要: A direct access storage device (DASD) includes a plurality of motion limiters and/or a continuous motion limiter projecting from at least one of the base and cover, each motion limiter having faces disposed in close proximity to and confronting opposite surfaces of a data storage disk adjacent a peripheral portion of the disk that does not contain data. Preferably, the motion limiters are disposed at several points about the periphery of the disk, and may be incorporated in a load/unload ramp and/or side rails of the DASD. The faces of the motion limiters are disposed relative to the disk so that when the DASD is subjected to an acceleration, the disk contacts at least one of the faces only at the peripheral portion of the disk, outside the data zone. Accordingly, the motion limiters prevent data zone and spindle bearing damage when the DASD is dropped.

    摘要: A shock-resistant actuator assembly for use in a data storage system is disclosed. The actuator assembly includes an actuator body, fabricated from a first type of metal, having a central aperture for pivoting on an actuator shaft. The actuator body includes at least one composite actuator arm extending outwardly from the actuator body. The composite actuator arm includes a primary arm member, also fabricated from the first type of metal, and a plating of a second type of metal having a thickness of at least 20 microns disposed on an upper and lower surface of the primary arm member. In one embodiment, the primary arm member is fabricated from aluminum and subjected to an electroless nickel plating process to deposit a sufficient thickness of nickel thereon to appreciably increase the stiffness of the primary arm member. In another embodiment, an actuator comb assembly includes a plurality of integral composite actuator arms for supporting a plurality of head suspension assemblies. The relatively thick plating of metal deposited on the primary arm member substantially enhances the stiffness and shock resistance of the composite actuator arm.

    摘要: An apparatus for supporting a recording/reading head and assembling a flex circuit in a disc drive preferably includes a suspension having a first end and a second end, and a stiffener coupled to the suspension at the second end, the stiffener extending substantially in parallel with the suspension. The apparatus further includes a flex circuit having a first portion and a second portion, the first portion is coupled to the suspension, and the second portion is coupled to the stiffener. The stiffener extends along the flex circuit. This allows one to readily locate the flex circuit in a subsequent process, such as a disc drive stack build process, so that the fabrication of the disc drive can be highly automated.

    摘要: An apparatus and method is presented for controlling initial load and unload wear on a slider by using a trailing edge extender. A slider for supporting a transducer proximate to a recording medium is disclosed. The slider includes a trailing edge extender positioned on a trailing edge to allow additional controlled wear to occur before a substrate of the slider contacts the recording medium. The trailing edge extender can be positioned at an outer corner on the trailing edge of the slider and at a transducer pad on the trailing edge of the slider. The trailing edge extender can include a depth of the step depth, cavity depth, or air bearing surface level depth. The method includes fabricating a trailing edge extender positioned on a trailing edge to allow additional controlled wear to occur before a substrate of the slider contacts the recording medium.
