摘要： A transducing head includes a first bias element, a second bias element, and a magnetoresistive sensor positioned between the first bias element and the second bias element. The first bias element and the second bias element are each formed of a permanent magnet material having a remanent magnetic moment in a range of about 200 to about 800 emu/cm3. In a preferred embodiment, the permanent magnet material is an alloy comprising iron, platinum, and at least one material selected from copper, silver, magnesium, lead, zinc, bismuth, and antimony.

摘要： A perpendicular magnetic recording medium includes a hard magnetic recording layer and a soft magnetic underlayer adjacent the hard magnetic recording layer. The soft magnetic underlayer includes first and second ferromagnetically coupled multilayer structures and a coupling layer positioned between the first and second multilayer structures for antiferromagnetically coupling the first and second multilayer structures. A magnetic disc drive storage system incorporating such a perpendicular magnetic recording medium and a method of making such a perpendicular magnetic recording medium are also included.

摘要： A contact pad includes a first layer of material with a first yield strength and a second layer of material with a second yield strength is laminated to the first layer. A third yield strength of the laminated composite of the first layer and the second layer exceeds the first yield strength and the second yield strength due to the Hall-Petch phenomenon. An overcoat covers an edge of the first layer and the second layer of the contact pad to prevent wear. A method of creating the contact pad or other microelectronic structure includes depositing a first layer of material with a first yield strength on a substrate. A second layer of material with a second yield strength is deposited on the first layer. An edge of the first layer and the second layer is coated with an overcoat material to prevent wear of the first and second layers.
