摘要： A rotary-type magnetic recording medium has servo patterns formed in servo pattern regions on a substrate by patterns including recording regions and non-recording regions. Burst signal units composed of the recording regions or the non-recording regions are formed in burst pattern regions in the servo pattern regions. The burst signal units are formed so that for at least one edge out of both edges along a direction of rotation of the magnetic recording medium, a center in the direction of rotation is positioned closer to the other edge than both ends in the direction of rotation, and a ratio of a length along a radial direction of the magnetic recording medium between both ends and the center of the one edge to a length along the radial direction between both ends of the one edge and both ends of the other edge is in a range of 0.2 or below.

摘要： A magnetic recording medium and a method for manufacturing the same are provided, which provide high surface recording density and high recording/reading performance. The magnetic recording medium is manufactured by forming an intermediate protective layer between a continuous recording layer and a mask layer, dividing the continuous recording layer to form divided recording elements and removing the mask layer while leaving the intermediate protective layer on the top of the divided recording elements. Further, gaps between the divided recording elements are filled with a non-magnetic material while leaving the intermediate protective layer on the top of the divided recording elements.

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.
