Document Type and Number:
Japanese Patent JP2001508224
Kind Code:
A
Abstract:
Reproducible texturing of magnetic recording media is enhanced by sputtering a buffer layer, such as Ni-P, on a nonmagnetic substrate, prior to sputtering a textured bump layer. A magnetic recording medium comprising a sputter textured metal layer and high coercivity is achieved by employing an underlayer, such as NiAl or FeAl, preferably a composite underlayer containing a chromium or chromium-alloy layer and a NiAl layer, on the sputter textured layer. Advantageously, the buffer layer, underlayer, textured bump layer, magnetic layer and carbon overcoat can be sputter deposited in a single apparatus.
