Method of fabricating a magnetic recording medium
View Patent ↗A method of fabricating a magnetic recording medium is disclosed, including a monomolecular film formation step of forming a monomolecular film on a substrate and a magnetic film formation step of forming on the monomolecular film a magnetic film for recording magnetic information. In the monomolecular film formation step, it is preferable to form a perylene-based organic monomolecular film.
1. A method of fabricating a magnetic recording medium, comprising:
a monomolecular film formation step of forming a monomolecular film on a substrate; and
a magnetic film formation step of forming on the monomolecular film a magnetic film for recording magnetic information,
wherein the monomolecular film formation step is an organic monomolecular film formation step of forming an organic monomolecular film on the substrate and the organic monomolecular film is a perylene-based organic monomolecular film.
2. The method of fabricating a magnetic recording medium as claimed in claim 1 , further comprising a step of forming a seed film for controlling a crystal state of the organic monomolecular film before the organic monomolecular film formation step.
3. The method of fabricating a magnetic recording medium as claimed in claim 2 , wherein at least one of Ag and Au is formed on the substrate in the step of forming a seed film.
4. A method of fabricating a magnetic recording medium, comprising:
a monomolecular film formation step of forming a monomolecular film on a substrate; and
a magnetic film formation step of forming on the monomolecular film a magnetic film for recording magnetic information, wherein the monomolecular film formation step is an organic monomolecular film formation step of forming an organic monomolecular film on the substrate; and
a heat-resisting intermediate film formation step of forming a heat-resisting intermediate film adsorbed selectively on the organic monomolecular film after the organic monomolecular film formation step.
5. The method of fabricating a magnetic recording medium as claimed in claim 4 , wherein at least one of Ge and Si is formed on the organic monomolecular film in the heat-resisting intermediate film formation step.
6. The method of fabricating a magnetic recording medium as claimed in claim 4 , further comprising a heat treatment step of performing a heat treatment after the heat-resisting intermediate film formation step.
7. The method of fabricating a magnetic recording medium as claimed in claim 6 , wherein the heat treatment is performed at or above a temperature at which the organic monomolecular film evaporates.
