  • Patent number: 8279558
    Abstract: An assembly includes a slider and a suspension assembly. The slider includes an air bearing surface and a slider mounting surface opposite the air bearing surface. There are a plurality of slider pads on the slider mounting surface. The suspension assembly includes a plurality of suspension pads on a suspension mounting surface. Each of the suspension pads is connected to one of the slider pads with a solder joint so that the slider mounting surface has at least one of a pitch, roll, or yaw angle with respect to the suspension mounting.
    Type: Grant

  • Patent number: 7151649
    Abstract: A solid-state actuation mechanism for use in a data storage system. The actuation mechanism includes an anchor fixedly attached to a housing of the data storage system, a spring member including a first end coupled to the anchor, a suspension coupled to a second end of the spring member, the suspension supporting a data head above a media surface, the suspension being biased by the spring member toward a first position, and an actuation component coupled to the suspension. The actuation component configured to apply an actuation force to the suspension to move the suspension laterally relative to the media surface.

  • Patent number: 7072147
    Abstract: A rotary actuator system includes an actuator block, a head mounting block, and a linkage arm connecting the actuator block and the head mounting block. The system further includes an actuator motor operatively connected to the actuator block for rotating a link. The linkage arm includes a drive link which is rotated by the actuator motor and a guide link spaced apart from the drive link. The drive link has a first end and a second end; the drive link is pivotally connected to the actuator block at the first end and connected to the head mounting block at the second end. The guide link has a first end and a second end; the guide link is connected to the actuator block at the first end and connected to the head mounting block at the second end.

  • Patent number: 6751047
    Abstract: A disc drive having a voice coil actuator with an attached suspension and head, the head including a micro-actuator. The micro-actuator having at least one natural frequency and at least one natural frequency time period. The voice coil actuator is adapted to attenuate a resonance of the micro-actuator at the at least one natural frequency using a stepped acceleration.

  • Patent number: 6535353
    Abstract: A disk drive system includes a base, a disk stack rotatably attached to the base, and an actuator assembly movably attached to the base. A ramp assembly includes a set of ramps for loading and unloading the sliders and transducing elements carried by the sliders to and from the disks in the disk stack. The ramp assembly is attached to the base. An actuator assembly is movably attached to the base of the disk drive. The actuator assembly moves the load springs and attached slider and transducers to various positions on the disk. The slider is a block of material having corners and edges. Sliders have a backside surface and an air-bearing surface. The slider also has at least one recess therein. One or more pads of shock absorbing material are positioned within at least one of the recesses in the slider. The pads are positioned within one or more recesses to prevent the corners or edges of the block of material near the air-bearing surface from contacting the disk.
