    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： A magnetic recording medium of the perpendicular type, for a disc drive. The magnetic recording material includes a Cobalt alloy layer interspersed with a noble metal layer. The initial graded material is paramagnetic to increase to the magnetic properties of perpendicular recording media into increase the signal to noise ratio. The final recording layer has 8-20 alternating multilayer of the Cobalt alloy and a noble metal.

    摘要： A data device may have at least a magnetic lamination with a thermal retention structure deposited on a substrate and configured to maintain a predetermined temperature for a predetermined amount of time. Such predetermined temperature and amount of time may allow for the growth of a magnetic layer with a predetermined magnetic anisotropy.
