摘要:
A slider for a magnetic disc drive includes a recess at the trailing edge of the slider. A thin film inductive magnetic transducer protrudes from a lower surface of the recess, the transducer having patterned magnetic poles. A barrier layer formed of an oleophobic, hydrophobic polymer having a surface energy lower than the surface tension of lubricant on the disc is bonded to the lower surface of the recess. One suitable polymer for the barrier layer is a fluorochemical acrylate.

In a disc drive with a disc spun by a motor and a head positionable over the disc, a disc drive controller alternately leaves the head landed on successive landing spots in a landing zone on the disc for selected stop intervals to remove an increment of lubricant from the head with each stop and then automatically lifts the head by spinning the disc for selected run intervals between the stop intervals so the head does not stick to the disc.

A clean suspension assembly for capturing particles carried by airflow along the suspension assembly includes an opening formed in the suspension assembly, and a particle capture device attached to the suspension assembly. In a further embodiment, the suspension assembly also includes a deflector located adjacent the opening.
摘要:
A magnetic disc drive system is disclosed. The disc drive system includes at least one substantially flat magnetic disc, at least one read/write head, at least one head stack assembly, at least one head gimbal assembly, and at least one suspension limiter. The suspension limiter is operatively connected to the head stack assembly. The distal end of the suspension limiter is positioned proximate but normally not in contact with the head gimbal assembly for preventing large head slaps in both operational and nonoperational mode.

A disc storage system includes a rotating disc and a transducer. The transducer is carried on a slider which is supported by an armature. The armature is used to move the slider radially across the disc surface whereby information may be read from or written to the disc surface of the transducer. The slider includes an air bearing surface which faces the disc surface. As the disc rotates, the air bearing surface causes the slider to “fly” over the disc surface. Pads are provided on the air bearing surface to improve operational characteristics of the system.

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.
