The track width performance of giant magnetoresistive (GMR) read heads defined by e-beam lithography was studied in a series of recording tests. Results on longitudinal media showed slow reductions of magnetic versus physical read widths below 100 nm

The thermal stability of coupled granular/continuous (CGC) perpendicular media is supported by fundamental modeling and experimental results, including spin-stand testing. By incorporating the interlayer exchange coupling into the model, the simulati

Perpendicular medium with an average grain size of 8.2 nm with 20 nm thickness has been produced by using a-CoCrPt/Ti/NiAl tri-layer structure. The signal-to-noise ratio improves with the addition of a NiAl seed layer. From the TEM image analysis, th

We studied coupled granular/continuous (CGC) perpendicular media consisting of a continuous multilayer structure and a granular layer. The addition of Co/Pt multilayers decreased the nucleation field from 200 to −1800 Oe and increased the squarenes

We have utilized antiferromagnetically coupled bilayer structures to magnetically tune hysteresis loop properties. A key element of this approach is the nonoverlapping switching field distribution of the two magnetic layers, which allows for the meas

The role of intergranular exchange coupling was experimentally investigated in a coupled granular/continuous (CGC) perpendicular medium structure. By changing the number of Co/Pt bilayers in the continuous layer, the degree of exchange coupling can b
