METHOD FOR MANUFACTURING MAGNETIC STORAGE MEDIUM, MAGNETIC STORAGE MEDIUM, AND INFORMATION STORAGE DEVICE

摘要

A magnetic storage medium having a high recording density is manufactured by a manufacturing method which does not deteriorate productivity.  A magnetic storage medium (10) is manufactured by a manufacturing method having a magnetic film forming step wherein a magnetic film (62) is formed on a substrate (61), and an inter-dot separating step wherein a separating region (62d) having saturated magnetization smaller than that of magnetic dots (62c) is formed between the magnetic dots (62c) by lowering saturated magnetization by locally implanting mixed ions of N2 + ions and N+ ions into areas of the magnetic film (62), excluding a plurality of areas to be the magnetic dots (62c) on which information is to be magnetically recorded, respectively.
