  • Patent number: 7408743
    Abstract: Apparatus and method for reading and writing information onto a hard disk drive is provided. The apparatus includes a suspension assembly for a hard disk drive. The suspension assembly includes at least two spring extensions that couple to a proximal portion of a load beam. These spring extensions are disposed by a vertical offset and couple to the load beam on opposite sides of a longitudinal axis of the load beam. The method for operating a disk drive apparatus includes following by a suspension assembly from a reference position to a second position a vertical movement of a rotating disk. The suspension assembly is predisposed to move from the reference position to the second position by a vertical offset between a first and second spring extensions of the suspension assembly. A read/write head coupled to the suspension assembly is in closer alignment to a selected track during the vertical movement in the second position than if the first and second spring extensions are disposed to be co-planar.

  • Patent number: 7408744
    Abstract: Method and apparatus for reduced contribution to suspension hinge stiffness of an electrical interconnect metal layer while retaining substantial impedance reductions from the metal layer use a sinuous pattern of removed and retained subregions of the metal layer selectively and distributively to ease bending of the metal layer and decrease its stiffness contribution while the retained metal layer subregions provide a substantial proportion of the impedance reduction normally provided by the metal layer.

  • Patent number: 7382582
    Abstract: Reduced cross talk between adjacent read and write circuits in a disk drive suspension interconnect results from interposing a ground trace conductor between the circuits and generally for the full length thereof and grounding the ground trace conductor suitably through a further metal layer on the opposite side of the insulative layer that supports the interconnect read and write circuits. The ground trace conductor or other metal strip located like ground trace conductor is used to define a precise locus for optical alignment of the electrical interconnect relative to the suspension flexure better than the insulative layer through more accurate etching of the metal strip. The first metal layer and the insulative layer may be made by an additive process.

  • Patent number: 7375930
    Abstract: A method (and apparatus) for operating a disk drive apparatus. The method includes moving a movable member about a fixed position to move a read/write head coupled to a slider to a selected track on a disk. The selected track is at least one of a plurality of tracks. The method includes adjusting a position of the read/write head using an actuating device integrated on the gimbal. The actuating step moves the read/write head relative in a manner normal to the track on the magnetic disk to align the read/write head on the track using a finer and faster alignment of the read/write head than the moveable support member.

  • Patent number: 7298590
    Abstract: A disk drive suspension and method uses two proximally cantilevered members to limit tongue movement in a suspension of a load beam having a beam portion and a flexure having a tongue. The suspension has a limiter structure comprising the two proximally cantilevered members arranged on the beam portion and the tongue respectively and intersecting for increasing engagement responsive to undue tongue travel against dislodgment.

  • Patent number: 7292413
    Abstract: A disk drive suspension has a base portion, a spring portion, and a beam portion carrying a slider at a disk. The base portion is a laminate of two inextensible outer layers and an inner layer that is extensible in shear. Microactuators that expand or contract are attached by their opposite ends in angled or parallel relation to the respective outer layers to shift the outer layers relative to each other as a function of shearing in the inner layer to shift the slider at the disk.

  • Patent number: 7280316
    Abstract: Techniques for reading and writing information onto a hard disk drive are provided. According to an embodiment of the present invention, a suspension assembly for a hard disk drive includes a load beam having a mounting region, a first spring extension on a first side of the load beam, and a rigid region. The suspension assembly also includes a hinge member having a second spring extension coupling the rigid region and the mounting region on a second side of the load beam. First and second spacers are disposed between the hinge member and the mounting region of the load beam and between the hinge member and the rigid region of the load beam, respectively. A vertical offset between the first and second spring extensions predisposes the rigid region to move from a first position to a second position in response to a disk flutter.

  • Patent number: 7236112
    Abstract: A self-tuning filter that is well suited for use as a output digital filter in a direct conversion delta-sigma transmitter is constructed as a high pass finite impulse response filter having a cutoff frequency of twice the desired carrier frequency. The filter is clocked using the same clock as used for the commutatation within the transmitter. The aliasing effect of the digital filter produces a passband centered around the carrier frequency which allows the information contained in the spectrum around the passband to be transmitted, while effectively filtering out the quantization noise produced by the commutation. When the commutator clock frequency is changed in order to change the carrier frequency, the passband automatically moves to track the new carrier frequency. The output filter may be constructed using series connected flip-flops with analog taps and an analog summer connected to respective Q and Q outputs, thereby producing an analog output.

  • Patent number: 7172113
    Abstract: A system and method enables a user such as a visitor to a facility to create a photographic identification card for himself. The user terminal prompts a user to enter identifying information including his name, and takes a photograph of the user. An identification badge is printed for the user upon predefined media. The identification card may be provided with a barcode and unique identification number. The user may be presented with a preview of the identification as the identification card is to be printed. Upon exiting the location, the user may scan the barcode or enter the unique identification number to sign out of the system and exit the location. A user activity log may be maintained at a server such that each time an identification card is created, printed or signed out, the log is updated with information regarding the user information, date, time, location or other information.

  • Patent number: 7128236
    Abstract: A label sheet assembly is provided with bar code information thereon defining the layout of the labels on the backing sheet. A versatile label dispenser apparatus advances the label sheets and deflects them over a peeling bar in one direction to partially separate the labels from the backing sheet; with the advancing action being determined by the bar code information. The label sheet assemblies are then deflected in the opposite direction, and are routed in a substantially flat condition to the output of the dispenser apparatus. The labels are partially dispensed, substantially vertically from the dispenser, and a substantial number of sensors are provided to sense when all of the labels have been removed; and then the dispenser advances the label sheet assembly to partially dispense the next row of labels. The bar code reader may also sense the leading edge of the label sheet assembly to accurately control the incremental advancing of the label sheet assembly.
