PROCESS FOR FORMING MAGNETIC FILM, PROCESS FOR FORMING MAGNETIC PATTERN, AND PROCESS FOR PRODUCING MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a process for forming a magnetic film having a part of different coercive force. SOLUTION: A thin film 4 principally comprising at least one of Fe and Co, and at least one of Pd and Pt is locally implanted with Ag ions 6 and heat treated. The part 7 implanted with Ag ions 6 becomes a part 9 having high coercive force and the part 8 not locally implanted with Ag ions 6 becomes a part 10 having low coercive force.
