MAGNETIC RECORDING MEDIUM AND ITS MANUFACTURING METHOD, AND MAGNETIC RECORDING AND REPRODUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a discrete track type perpendicular magnetic recording medium which is excellent in crystal orientation and perpendicular magnetic anisotropy of a magnetic recording layer, obviates deterioration of the magnetic characteristics of the magnetic recording layer due to processing, is inexpensive in manufacturing cost, and does not require a complicated manufacturing process and to provide its manufacturing method. SOLUTION: The perpendicular magnetic recording medium has rugged pattern structure comprising projecting parts corresponding to the positions of data tracks 55 for recording magnetic information and recessed parts corresponding to the positions between the data tracks on the surface on a medium floating surface side of a soft magnetic backing layer 52 and is laminated with a base layer 53 and the magnetic recording layer 54 for crystal orientation control along the rugged pattern structure on the projecting parts and the recessed parts without omission.
