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 read head for use with magnetic recording media having a plurality of magnetic tracks includes a read sensor, first and second magnetic lead shields for improving track resolution, and first and second magnetic shields for improving linear resolution. The read sensor is formed on a side wall of one of the first and second magnetic lead shields using a technique such as ion beam deposition for enhanced film growth rate on the side wall. A magnetic disc drive storage system incorporating the read head and a method of making the read head are also included.

摘要： A dual spin valve read head includes first and second spin valve stacks configured to operate in a current perpendicular to plane (CPP) mode. The first and the second spin valve stacks each include a free layer. A spacer is positioned adjacent the free layers of the first and the second spin valve stacks and spaces the first spin valve stack apart from the second spin valve stack.

摘要： Multilayer permanent magnet films comprising at least two permanent magnet layers separated by an interlayer are disclosed. In one embodiment, the multilayer permanent magnet film includes an interlayer deposited on a first permanent magnet layer, a seed layer deposited on the interlayer, and a second permanent magnet layer deposited on the seed layer. The permanent magnet layers may comprise a material such as CoPt, while the seed layer may comprise a material such as TiW. The interlayer may comprise a material such as Ta. The multilayer permanent magnet films possess favorable properties such as high magnetic coercivity (Hc) and high remnant magnetization (MR) at thicknesses which yield high magnetic fields. The films may be used in applications such as current perpendicular to the plane (CPP) magnetic sensors in which the multilayer permanent magnet film is used to magnetically bias the sensor.
