发明名称 MAGNETIC RECORDING MEDIUM, MAGNETIC RECORDING AND REPRODUCING APPARATUS, AND METHOD FOR MANUFACTURING MAGNETIC RECORDING MEDIUM
摘要 There is provided a magnetic recording medium which can be manufactured at a high production efficiency, and in which a protruding section constituted of a magnetic layer can be separated by a recessed separating region, and stability for the floating properties of the magnetic head is excellent, the magnetic recording medium including, on at least one surface of a disc-shaped substrate, an annular magnetic recording region (A); and a landing region (B) arranged along the edge portion of the magnetic recording region (A); a data region (41) in which a data pattern (45) configured from a protruding section (43a) constituted of a magnetic layer and a recessed separating region (44a) formed in the periphery of the protruding section (43a) is provided, and a servo information region (42) in which a servo pattern (46) configured from the protruding sections (43b) and (43c) and the separation region (44b) and having a different shape from that of the data pattern (45) when seen in plan view, in the magnetic recording region (A); and an uneven pattern (47) having a protruding section (43d) with the same shape as that of the protruding section (43a) in the data pattern (45) and provided in at least a portion of the landing region (B).
