ABSTRACT:
A method for manufacturing a magnetic recording medium comprising a first step in which a first magnetic layer, having a repetitive magnetization pattern formed by a magnetic head over its entire surfaces is formed on a base layer. The base layer and the first magnetic layer together form a first laminated body. In a second step, a second magnetic layer in which magnetic particles are oriented in a predetermined direction and which is thermally magnetizable is formed on a second base layer. The second base layer and the second magnetic layer form a second laminated body. In a third step, the second laminated body is bonded to the first laminated body.
