摘要： A magnetic recording medium is provided, which has a recording layer formed in a concavo-convex pattern and makes it possible to obtain the stable flying characteristics of a head. In the magnetic recording medium, concave portions between recording elements are filled with a non-magnetic material. Thus, the surface of the magnetic recording medium takes a concavo-convex shape which is different from the concavo-convex pattern of the recording layer. Also, the arithmetical mean deviation of the assessed profile of the concavo-convex shape in the surface is restricted to 1 nm or less.

摘要： A magnetic recording medium capable of preventing contact with a magnetic head for use in recording or reproduction, during recording or reproducing of record data. The magnetic recording medium has a disk-shaped substrate having a surface formed with an annular data-recording area, an outer area outward of the data-recording area, and an inner area inward of the same. The annular data-recording area has a plurality of tracks separated from each other by concentric separating grooves. At least one of the outer area and the inner is subjected to lift-adjusting treatment for enabling adjustment of lifts applied to the magnetic head. This makes it possible to effectively prevent the magnetic head from being inclined to be brought into contact with the magnetic recording medium.

摘要： There is provided a stamper on which stamper-side concave/convex patterns are formed and which is capable of manufacturing an information recording medium on which at least servo patterns are formed by concave/convex patterns. First convex parts that are continuously formed along a direction corresponding to a radial direction of the information recording medium are formed in the stamper-side concave/convex patterns. Each of the first convex parts is formed so that a height of a part of the first convex part from a reference plane, which is set between a front surface and a rear surface of the stamper, to protruding end of the first convex part increases as a length of the part of the first convex part in a direction corresponding to a circumferential direction of the information recording medium increases.

The non-recording element is formed as convex portion of the concavo-convex pattern at an outer circumferential end and/or an inner circumferential end. The recording elements are formed as convex portions of the concavo-convex pattern in a region other than a region where the non-recording element is arranged. The magnetic recording medium further has a non-magnetic material with which concave portions of the concavo-convex pattern are filled and which covers the non-recording element, and a protective layer formed over the recording layer and the non-magnetic material.
