Abstract

Thin film media characterized by the utilization of a substantially peritectic seed alloy layer which is sputter deposited so as to provide dispersed, substantially peritectic and homogenous globules underlying subsequently deposited media layers. These media layers may include a metal layer such as chrome and a magnetic layer such as an alloy of cobalt, chromium, and platinum and possibly other ingredients.
