Magnetic recording medium and method for producing the same

摘要

A patterned magnetic recording medium, accessible by a magnetic recording head, including a plurality of tracks, a width direction of each track and that of the magnetic recording head being of a skew angle. The patterned magnetic recording medium includes a plurality of magnetic dots, each corresponding to a recording bit, formed on a non-magnetic material. The plurality of magnetic dots are arranged in a plurality of arrays, each array corresponding to one of the tracks. Every N adjacent magnetic dots of the array define a polygon, one side thereof being parallel to the corresponding track, and another side thereof being parallel to a direction determined by the skew angle of the corresponding track.

1. A patterned magnetic recording medium, including a plurality of magnetic dots, each corresponding to a recording bit, formed on a non-magnetic material, the patterned magnetic recording medium comprising:
an aluminum layer on a substrate made of the non-magnetic material; and a plurality of polygonal cavity portions in the aluminum layer, wherein each of the plurality of polygonal cavity portions extends across a width of more than one said recording bit in a track direction of the recording medium, and wherein the plurality of magnetic dots are formed only in corners of the plurality of polygonal cavity portions.
