摘要:
The present invention provides a transducing device. The transducing device includes a transducing element. The transducing device further includes at least one heating element formed within the transducing device and spaced a sufficient distance from the transducing element to substantially reduce a temperature effect on the transducing element.
摘要:
The present invention is a novel method and apparatus for determining head media modulation in a magnetic data storage and retrieval system. The magnetic data storage and retrieval system includes a magnetic disc with a stored signal and a transducing head for reading a readback signal based on the stored data. The system includes a data acquisition and processing circuit. The processing circuit generates a dynamic harmonic ratio for the readback signal. The processing circuit also generates a head media modulation signal as a function of time from the dynamic harmonic ratio.

The present invention provides a transducing device. The transducing device includes a transducing element having a read element and a write element. The transducing device further includes at least one heating element formed within the transducing device and spaced apart from the heating element a sufficient distance to keep the at least one heating element from influencing a temperature of the transducing element.
摘要:
An abrasive article is provided. The article includes (a) a flexible backing having opposing first and second surfaces; (b) an abrasive layer comprising plurality of abrasive particles disposed on the first surface of the flexible backing; and (c) an adhesive layer comprising load bearing particles and an adhesive matrix, the adhesive layer disposed on the second surface of the polymer layer. At least a portion of the load bearing particles is substantially enveloped in the adhesive matrix and is in contact with the second surface of the polymer substrate.

The present application is directed to a slider supporting apparatus for flying a slider of a hard disk drive in the manufacturing process to provide electrical performance characteristics. The present invention discloses an integrated design including the electrical interconnect, the gimballing mechanism, the preload mechanism and the slider supporting mechanism integrated into a single supporting structure.
摘要:
This invention relates to methods for plate dressing using slurry charged with abrasives and soft polymeric or metallic micro-nano spheres additives to produce substantially uniform abrasive height. Additionally, methods for plate dressing using slurry charged with abrasives and self-assembled polymers to produce substantially uniform abrasive height are disclosed.
摘要:
A method of making an abrasive article including the step of preparing a master plate with a surface having a shape. Depositing a spacer layer on the surface of the master plate. A slurry containing an adhesive and abrasive particles is deposited on a surface of the spacer layer. A substrate embedded with abrasive particles having a surface generally complementary to the surface of the master plate is fabricated. A spacer layer is formed by various method controlled the height of the protruded abrasive particles. The master plate and the spacer layer are separated from the substrate to expose abrasive particle protruding a substantially uniform height. An abrasive article made according to this method is also disclosed.
摘要:
The application discloses processes for fabricating a slider or head for a data storage device. The processes disclosed provide a transducer portion that is separated from a slider body by a gap. In an illustrated embodiment, actuator elements are fabricated in the gap to adjust a position of the transducer portion relative to the slider body.
摘要:
An air bearing for a slider including cooperating raised bearing surfaces or portions along a trailing edge portion of the slider. The cooperating raised bearing surfaces or portions are formed on a stepped bearing surface which is elevated above a recessed bearing surface. The cooperating raised bearing surfaces or portions form raised rails or rails portions or a raised center pad or raised center pad portion on the stepped bearing surface to reduce cross curve sensitivity.
