Patent ID: 7247510

Claim:
A method of fabricating a patterned magnetic recording medium in which nanostructures each comprising a multilayered film are surrounded by inorganic insulators in such a way as to be laid out apart from one another at substantially even pitches and are provided on a substrate by performing, in order: forming a multilayered film showing a tunneling magnetoresistance effect or a multilayered film showing a giant magnetoresistance effect; forming a resist pattern on said multilayered film; etching said multilayered film using said resist pattern as a mask; removing said resist pattern; forming an inorganic insulating film on said etched multilayered film; planarizing said inorganic insulating film by chemical mechanical polishing (CMP); and wherein forming said resist pattern includes using a die in which a predetermined pattern is formed in advance on another substrate different from the one on which said resist pattern is formed.
