摘要： A stamper according to an embodiment includes a guide including: a first portion provided in regions to be boundaries between the servo region and the data regions in the bit-patterned medium, the first portion extending in a radial direction; and a second portion connected to the first portion, the second portion having protrusions regularly arranged at predetermined intervals in the radial direction, each of the protrusion having and being located on sides of regions to be the data regions, wherein, of angles formed between at least one of two sides of the triangular shape and a straight line extending in the radial direction, the smaller angle is in the range of 10 to 50 degrees, the two sides extending from a vertex of one of the protrusions.

摘要： A stamper of an embodiment includes: a base portion having a main surface; and a plurality of guides arranged on the main surface in mutually different first and second directions and serving as references of arrangement of a plurality of self-assembled dots. A distance between the guides in a third direction is within a range of an integer m1 ±0.05 times of a pitch of the plural self-assembled dots. The third direction corresponds to a third vector obtained by combining a first vector corresponding to the arrangement of the guides in the first direction and a second vector corresponding to the arrangement of the guides in the second direction. A distance between the plural guides in the first direction falls out of a range of an integer m2 ±0.15 times of the pitch of the plural self-assembled dots.
摘要翻译：实施例的压模包括：具有主表面的基部; 以及在相互不同的第一和第二方向上布置在主表面上的多个引导件，并且用作多个自组装点的布置的参考。导向件之间的距离在第三方向上在多个自组装点的间距的整数m1±0.05倍的范围内。第三方向对应于通过组合与第一方向上的引导件的布置相对应的第一矢量和对应于第二方向上的引导件的布置的第二矢量而获得的第三矢量。第一方向上的多个引导件之间的距离落在多个自组装点的间距的整数m2±0.15倍的范围内。
