Master carrier for magnetic transfer

摘要

A master carrier for magnetic transfer is equipped with a substrate with a land/groove pattern of lands and grooves, and a magnetic layer formed on the land/groove pattern. The adhesion between the substrate and the magnetic layer is 1.2x109 N/m2 or greater. A first oxygen concentration Do at the magnetic layer formed on the land is reduced gradually toward the direction of the depth of the substrate and is greater than a second oxygen concentration Dh at the magnetic layer formed on the groove.
