Master information carrier for magnetic transfer and magnetic transfer method

摘要

A master information carrier (3) for magnetic transfer to an in-plane magnetic recording medium includes a base sheet (3a) having an irregularity pattern (31) representing information to be transferred to an in-plane magnetic recording medium and a magnetic layer (3b) formed along the irregularity pattern. The thickness ( da1 ) of the magnetic layer on the upper surface of a protruding portion of the irregularity pattern and the thickness ( da2 ) of the magnetic layer on each of the side surfaces (31s) of the protruding portion satisfy the following condition,
