A slider body characterized by rounded corners and edges and smooth surfaces, formed by polishing with a polymeric fiber and a free abrasive slurry of submicron particles.

Slider having rounded corners and edges, and method for producing the same

A method for producing magneto resistive heads includes the steps of positioning at least two magneto resistive elements in spaced relation to one another and placing the at least two magneto resistive elements in an ion milling environment where material is removed nonselectively from items in the environment. A property of at least two of the plurality of magneto resistive elements is monitored. In response to monitoring, one of the at least two magneto resistive elements is dynamically covered to prevent additional removal of material from the covered magneto resistive element.

The slider and method of the present invention relate to a slider for a disc drive. The slider includes a substrate having a cavity and a filler within the cavity. The slider further includes a transducer that is positioned near the filler. The design facilitates controlling the relative thermal expansion between the transducer and substrate of the slider that is near the transducer. Compensating for the thermal expansion of the transducer provides a more consistent fly height of the slider during operation of the disc drive. In addition, the design adjusts the air-bearing surface of the slider such that the transducer does not extend below the rest of the slider as the transducer expands.

A head testing apparatus is provided for testing a data recording head. The apparatus includes a test volume, a magnetic field source, a holder and a thermoelectric source. The test volume is adapted to receive the head, and the magnetic field source is positioned to generate a magnetic field within the test volume. The holder is adapted to hold the head and position the head within the test volume. The thermoelectric source is positioned to contact the head when the head is positioned within the test volume by the holder.

Thermal slider level transfer curve tester for testing recording heads

For a tape contact face to be formed in a thin-film magnetic head having at least one transducing element, by removing material, a reference plane (29) corresponding to the tape contact face is detected by means of a plurality of markers (27A-27J) juxtaposed in a layer and extending transversely to the tape contact face, which markers have first end portions (27A1-27J1) pointing in one direction and second, spatially separated end portions (27A2-27J2) pointing in an opposite direction, with the second end portions located at different distances from the reference plane, inclined with respect to the reference plane, and adjoining each other steplessly.
