Abstract
We have fabricated a magnetic rectangular block array of 130 Gblock/in.(2) with a block-size-to-period ratio of 0.85 by using focused ion beam lithogr aphy. Each block has perpendicular crystal magnetic anisotropy and a single domain structure. Its advantage as patterned media is discussed in conjunc tion with thermal stability in recorded magnetization, reading signal, and area density. (C) 2001 American Institute of Physics.
