Abstract
A recording medium comprising a hydrophilic film formed on a substrate, recording domains formed directly on the hydrophilic film so as to form a predetermined pattern, each recording domain being made of an organic dye molecule and having a size of 50 nm or less, and an isolation region surrounding the recording domains, the isolation region being made of an organic molecular film.
Claims12
A recording medium comprising;
- an inorganic material film formed on a substrate;
- and
- recording domains buried in said inorganic material film so as to form a predetermined pattern, each recording domain being made of a recording material selected from an organic dye molecule and an inorganic phase-change material, and having a size of 50 nm or less.
A method of manufacturing a recording medium, comprising the steps of:
- forming an inorganic material film on a substrate;
- forming pits in said inorganic material film so as to form a predetermined pattern;
- filling said pits with a recording material selected from an organic dye molecule and an inorganic phase-change material;
- and
- removing an excessive recording material out of said pits.
