摘要： Multilayer magnetic structures comprising composite layers and spacer layers are disclosed. The composite layers include a discontinuous magnetic phase such as Co, Ni or Fe platelets, and a continuous nonmagnetic phase such as C, AlOx, SiOx, ZrOx, Cu, Ag and Au. The spacer layers may comprise Pt, Pd, Au or the like. The composite layers and spacer layers may be made by sputtering. The multilayer structures are useful as magnetic recording layers of magnetic recording media. In one embodiment, the recording media comprises a perpendicular magnetic recording medium including a substrate, a soft magnetic underlayer, a seed layer and the multilayer structure.

摘要： A magnetic recording medium for communication with a transducer moving relative to the recording medium along a line of relative transducer motion. The magnetic recording medium has a substrate with a substrate surface, and a seed layer on the substrate surface. The magnetic recording medium also has a soft magnetic underlayer on the seed layer. The soft magnetic underlayer includes a magnetic material having a magnetic moment larger than 1.7 teslas. The soft magnetic underlayer has a texture that provides a magnetic easy axis that has an easy axis alignment parallel to the line of relative transducer motion. A magnetic storage layer is on the soft magnetic underlayer.

摘要： An apparatus for measuring a distance such as, for example, a fly height distance. An apparatus includes a slider having an air bearing surface and an optical condenser assembly spaced apart from the air bearing surface of the slider. The optical condenser assembly includes an optical cap and an optical substrate having a first surface and a second surface. The first surface is spaced apart from the optical cap and the second surface is spaced apart from the air bearing surface of the slider.
