MAGNETIC RECORDING MEDIUM MANUFACTURING METHOD AND MAGNETIC RECORDING/REPRODUCTION DEVICE

摘要

Provided is a method for manufacturing a magnetic recording medium having a magnetic recording pattern magnetically separated. The method includes the following three steps performed in this order: [1] a step for forming a magnetic layer on a non-magnetic substrate; [2] a step for removing a magnetic layer surface portion of a region for magnetically separating the magnetic layer; [3] a step for exposing to reactive plasma or reactive ions, the surface of the magnetic layer region exposed by removing the magnetic layer surface layer portion so as to reduce the coercive force and the residual magnetization of the magnetic layer region, so that the magnetic layer region having the reformed magnetic characteristic forms a magnetic recording pattern magnetically separated. By using this method, it is possible to manufacture a magnetic recording medium having no write blur upon magnetic recording, at a high productivity.
