Patent number: 7151649Abstract: 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.Type: GrantFiled: February 5, 2003Date of Patent: December 19, 2006Assignee: Seagate Technology LLCInventors: Zine-Eddine Boutaghou, Joel David Limmer

Patent number: 7072147Abstract: 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.Type: GrantFiled: June 20, 2003Date of Patent: July 4, 2006Assignee: Seagate Technology LLCInventors: Joel David Limmer, Zine-Eddine Boutaghou, Wayne Allen Bonin

Patent number: 6535353Abstract: 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.Type: GrantFiled: November 6, 1998Date of Patent: March 18, 2003Assignee: Seagate Technology LLCInventors: Zine Eddine Boutaghou, Joel David Limmer, Jorge Vicente Hanchi, Lance Eugene Stover
