摘要： A method for manufacturing a magnetic recording medium is provided, by which the magnetic recording medium having a recording layer formed into a predetermined concavo-convex pattern and an adequately flat surface can be efficiently and certainly manufactured. Particles of a non-magnetic material are applied to a member to be processed from a direction relatively inclined with respect to a normal to the surface of the member to be processed. Also, the member to be processed is rotated around a central axis which is inclined with respect to an application direction of the particles of the non-magnetic material, to fill recessed portions of the concavo-convex pattern with the non-magnetic material.

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.

摘要： A magnetic recording medium is provided, which includes a recording layer formed in a concavo-convex pattern to achieve high areal density and can ensure good recording and reproduction characteristics so as to provide high reliability. The magnetic recording medium has a substrate and a recording layer formed in the predetermined concavo-convex pattern over the substrate. The recording layer has a non-recording element and recording elements. 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.

摘要： A magnetic recording medium having a recording layer formed in a concavo-convex pattern, which can allow a head to have stable flying characteristics. The recording layer is formed in a concavo-convex pattern, and concave portions of the concavo-convex pattern of the recording layer are filled with a non-magnetic material. The relationship of S≦3.6×R holds, when R represents a concavo-convex ratio obtained by dividing an area of convex portions in a surface by an area of the concave portions in the surface, and S represents a difference in height between a concavity and a convexity of the surface. In the magnetic recording medium, an arithmetical mean deviation of the assessed profile of the surface is limited to 0.3 nm or more.

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.
