METHOD OF FORMING MAGNETIZATION PATTERN OF MAGNETIC RECORDING MEDIUM, MAGNETIC RECORDING MEDIUM, MAGNETIC RECORDER, AND MASK

摘要

PROBLEM TO BE SOLVED: To provide a magnetization pattern forming method which can efficiently form a fine magnetization pattern at low cost by providing a mask with high energy ray resistance, in the magnetization pattern forming technique which forms the magnetization pattern on a magnetic recording medium by using a combination of local heating and external magnetic field application. SOLUTION: The magnetization pattern forming method comprises: a step for radiating the energy ray to the magnetic recording medium which has a magnetic layer on a substrate via the mask, and heating the irradiated part of the magnetic layer; and a step for applying the external magnetic field to the magnetic layer. The mask has a transmissive substrate and a non- transmissive layer to the energy ray. The substrate has a recessed part corresponding to the magnetization pattern to be formed, and the non-transmissive layer is formed at least on the recessed part. COPYRIGHT: (C)2003,JPO
