Patent number: 8192087Abstract: A fluid dynamic bearing formed by a microelectromechanical systems (MEMS) wafer-level batch-fabrication process is provided. The process results in a high performance and high reliability fluid dynamic bearing having features including higher bearing lifetime at high RPM, improved bearing stiffness, durability and thrust/restoring forces capabilities. The present invention is especially useful with small form factor disc drive memory devices having constraints in motor height, such as a 2.5 inch disc drive, requiring high performance including high rotational speed and large areal density. A sacrificial layer is utilized in the process to simultaneously form symmetrical facing surfaces of relatively rotatable components. The facing surfaces define, therebetween, a desired feature, such as a journal bearing, a thrust bearing, a fluid channel, a fluid reservoir, a capillary seal, pressure generating grooves, and other profile geometries.Type: GrantFiled: May 27, 2009Date of Patent: June 5, 2012Assignee: Seagate Technology LLCInventors: Roger L.

Publication number: 20080174919Abstract: A disc drive head actuator includes a suspension structure and a slider integrated with the suspension structure. The actuator is one of at least two actuator assemblies batch-fabricated on a common substrate. The head actuator may be fabricated using mircofabrication techniques. The head actuator may have a reduced size, including package height relative to conventionally manufactured disc drives. Using mircofabrication and/or batch fabrication techniques provides reduced tolerances, which allows for increased actuation forces and/or reduced power consumption. Some embodiments include four-bar linkage actuators, which increase lateral stiffness of the actuator, allowing for a precise motion of the head relative to a media surface.Type: ApplicationFiled: January 23, 2007Publication date: July 24, 2008Inventors: Andrew D.

Patent number: 7277257Abstract: A transducer-level microactuator selectively positions a transducer portion of a slider radially with respect to circumferential data tracks of a rotatable disc. The slider includes a slider body having a leading edge and a trailing edge, a transducer body and a flexure body. The transducer body is spaced from the trailing edge of the sliding body and includes at least one transducer element. The flexure body extends from the trailing edge of the slider body and includes a first anchor point connected to the slider body and a second anchor point connected to the transducer body. The basecoat layer is deposited on the trailing edge of the slider body and substantially surrounds the flexure body wherein a gap separates the flexure body from the basecoat. A first actuation assembly is formed on the basecoat and a second actuation assembly is formed on the transducer body adjacent the slider body.Type: GrantFiled: December 5, 2003Date of Patent: October 2, 2007Assignee: Seagate Technology LLCInventors: Roger L.
