  • Patent number: 8767351
    Abstract: The presently disclosed technology describes systems and methods for attaining a ball bond using less than 1 thousandth of an inch diameter gold wire using ultrasonic bonding energy and without heating an underlying bonding pad. The ball bond allows the use of particularly small bonding pads that are particularly close to adjacent microelectronic structures that limit the use of other bonding techniques that have shallow take-off angles.

    Abstract: An apparatus includes a crystalline substrate. A cleaving guide on the substrate is positioned over a cleave plane of the crystalline substrate and positioned in a known location with respect to a feature of an electronic device on the substrate. Cleaving of the substrate along the cleave plane changes a physical characteristic of the cleaving guide and measurement of the physical characteristic provides a parameter representative of the relative position of the cleave plane and the cleaving guide.

  • Patent number: 8192087
    Abstract: 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.

  • Publication number: 20080174919
    Abstract: 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.

  • Publication number: 20080174899
    Abstract: A device comprises a recordable disc, a substrate adjacent to the recordable disc, and an actuation mechanism fixed to the substrate. The recordable disc includes a base layer and a recordable layer on the base layer. Additional electrodes or magnetic components may be placed on the base layer to provide electromagnetic or electrostatic forces to rotate the recordable disc when acted on by the actuation mechanism. As an example, the invention may utilize MEMS techniques in order to integrate a disc and motor of a disc drive as a common component.

  • Publication number: 20080174906
    Abstract: In general, the invention is directed to techniques for integrated interconnects with a set of disc drives. The interconnects allow for a set of disc drives to be positioned in an array; for example, as set of disc drives may be stacked to communicate with a device through a single interface of the device. The interconnects may be formed as vias within the housing of the disc drives. Vias may produced using MEMS techniques, e.g., electroplating, as part of the manufacturing processes of the disc drive itself.

  • Publication number: 20080174907
    Abstract: A micro-electromechanical systems (MEMS) disc drive includes high-precision and integrated components to allow for increased functionality, robustness and reduced size as compared to currently produced disc drives. Integrating multiple subcomponents of the disc drive using batch processing provides low manufacturing costs. Furthermore, using MEMS techniques, new features can be added to disc drives. For example, an environmental control component, an accelerometer and/or a thermometer may be integrated into the housing of the disc drive.

  • Patent number: 7277257
    Abstract: 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.

  • Patent number: 7254885
    Abstract: A method is used for fabricating sliders for use in a disc drive actuation system, the sliders having bonds pads formed on either a top surface or side faces of the slider. The method comprises providing a substrate having a top surface. Trenches are formed in the substrate and filled with a bond pad material to form slider bond pads. Excess bond pad material is removed from the trenches such that the slider bond pads are flush with the top surface of the substrate. A transducer is fabricated on the top surface of the substrate. Finally, the slider bond pads are exposed.
