Patent ID: 7115208

Claim:
A method of manufacturing a recording medium, comprising: forming on a disk substrate a continuous or intermittent groove region or a band region containing a specified chemical component concentrically or spirally, which corresponds to a recording track band, the groove region or the band region being defined by isolation regions formed concentrically or spirally; forming a two-dimensional regular array structure of self-ordering molecules or fine particles in the groove region or the band region; and forming recording cells corresponding to the regular array structure including forming a recording layer on the disk substrate, forming a first film on the recording layer, patterning the first film to form a concentric or spiral pattern corresponding to the isolation regions and a concentric or spiral groove region corresponding to the recording track band, forming a two-dimensional regular array structure of self-ordering molecules or fine particles in the groove region, etching the recording layer using the concentric or spiral pattern of the first film and the self-ordering molecules or fine particles as a mask to form the isolation regions made of the recording layer and the recording cells; and forming a non-recording material between the recording cells.
