Specification

CLAIMS
1. An optical recording medium having an inorganic
recording film, characterized in that
the optical recording medium comprises a transparent conductive recent to said inorganic recording film,
wherein said : recording film has
a first recorti. containing "titanium (Ti) and
a second recording film containing an oxide of germanium (Ge), and
said transparent conductive film is provided on the side of said second recording film.
2. The optical recording medium according to claim 1, characterized in that said transparent conductive film contains at least one kind of an oxide of tin (Sn; and an oxide of indium (In).
3. The optical recording medium according to claim 1, characterized in that said second recording film further contains tin (Sn).
4 . The optical recording medium according to claim 1, characterized in that a thickness of said transparent conductive film is 1 to 5 ran.
5. A manufacturing method of an optical recording medium having an inorganic recording film, characterized by comprising the steps of:
forming a first recording film containing titanium (Ti);
forming a second recording film which is adjacent to said first recording film and contains an oxide of germanium (Ge); and
forming a transparent conductive film, adjacent to said second recording film.
