摘要： A servo pattern is formed in a servo pattern region on at least one surface of a substrate of a magnetic recording medium by a concave/convex pattern including a plurality of convex parts, at least protruding end parts of which are formed of magnetic material, and at least one concave part. The servo pattern region includes an address pattern region and a burst pattern region. The at least one concave part is formed in the servo pattern region so that a larger of an inscribed circle with a largest diameter out of inscribed circles on protruding end surfaces of the convex parts formed in the address pattern region and an inscribed circle with a largest diameter out of inscribed circles on protruding end surfaces of the convex parts formed in the burst pattern region is an inscribed circle with a largest diameter out of inscribed circles on protruding end surfaces of the convex parts formed in the servo pattern region.

摘要： The recording layer is made of both magnetic particles containing Co, Cr, and Pt and a nonmagnetic material containing Cr present among the magnetic particles. The recording element has an uneven Cr distribution such that the ratio of the number of Cr atoms that constitute the recording element to the total number of Co, Cr, and Pt atoms that constitute the recording element is less at the sidewall portion of the recording element than at the center portion of the recording element. The relationships given by Expressions (I) and (II) below are satisfied; Hnc

摘要： A method for manufacturing a magnetic recording medium is provided which can sufficiently reduce variations in surface roughness even in the simultaneous presence of a region of a relatively wide concave and convex portion and a region of a relatively narrow concave and convex portion in the recording layer. The method includes the steps of etching a recording layer based on a (first) mask layer to process it in a concavo-convex pattern, and depositing a filler over the recording layer and the mask layer to fill a concave portion with the filler. In between those steps, provided is the step of removing part of the first mask layer over a recording element (a convex portion of the recording layer) by dry etching in which an etching rate for the mask layer is higher than that for the recording layer so that the mask layer remains over the recording element.
摘要翻译：提供了一种用于制造磁记录介质的方法，即使在相对较宽的凹凸部分的区域和记录层中相对窄的凹凸部分的区域同时存在的情况下，也可以充分减小表面粗糙度的变化。该方法包括以下步骤：基于（第一）掩模层蚀刻记录层，以凹凸图案处理该记录层;以及在记录层和掩模层上沉积填料以填充填料的凹部。在这些步骤之间，提供了通过干蚀刻在记录元件（记录层的凸部）上去除部分第一掩模层的步骤，其中掩模层的蚀刻速率高于记录层的蚀刻速率使得掩模层保留在记录元件上。

摘要： There are provided a next process-determining method capable of determining a next process to be carried out next objectively and at the same time in a short time period, as well as an inspecting method and apparatus which are capable of carrying out a predetermined inspection as to an object to be inspected according to the next process-determining method. 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.
