PRODUCTION PROCESS AND PRODUCTION SYSTEM OF MAGNETIC RECORDING MEDIUM

摘要

There is provided a process for efficiently producing a magnetic recording medium having good magnetic characteristics by suppressing deviation in the machining shape and magnetic deterioration of a split recording element. Ion beam etching is employed as a dry etching method of a continuous recording layer (20). A resist layer (26) is removed before dry etching the continuous recording layer (20). Diamond-like carbon is employed as the material of a first mask layer covering the continuous recording layer.
