发明名称 MAGNETIC RECORDING MEDIUM AND MAGNETIC RECORDING AND REPRODUCING APPARATUS
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a magnetic recording medium to clearly show magnetic difference between recording element and concave part at the boundary of them and to ensure higher manufacturing efficiency. <P>SOLUTION: The magnetic recording medium 10 includes: a substrate 12; a recording layer 14 formed on the substrate 12 with the predetermined convex-concave pattern, wherein the convex part of the convex-concave pattern constitutes a recording element 14A; and a filling part 18 for filling the concave part 16 between the recording elements 14A. The center part 16A at the bottom surface of the concave part 16 is protruded in the opposite side of the substrate 12 rather than the end part 16B at the bottom part of the concave part 16. <P>COPYRIGHT: (C)2010,JPO&INPIT</p>
