    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 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.

A sample object is digitized to sample data formed by digital data. The sample data is compressed into compressed sample data according to a predetermined data format. There is calculated a difference data amount between a data amount of the compressed sample data and a data amount of reference data formed by digitizing and compressing a reference sample object in the same manner as the sample object is processed. Which of a plurality of predetermined numerical ranges the difference data amount belongs to is identified. A predetermined process is determined which is associated with the identified numerical range in advance as a next process to be carried out next.

    摘要: A method for manufacturing an information recording medium, a method of transferring a concavo-convex pattern, and a transfer apparatus are provided which are capable of curing a resin material with reliability even when using a light-transmitting stamper repeatedly. A stamper made of a light-transmitting resin, having a predetermined concavo-convex pattern formed on its transfer area, is inspected for an optical characteristic. The stamper is brought into contact with an energy-ray curable resin material applied to an object to be processed, thereby transferring the concavo-convex pattern to the resin material, and the resin material is irradiated with an energy ray through the stamper so that the resin material cures. The stamper is used a plurality of times to repeat these steps a plurality of times, thereby manufacturing a plurality of information recording media.
