Claims
- 1. A method of manufacturing an optical recording element, which comprises the steps of:
- preparing a heat-resistant organic resin substrate sheet;
- taking said substrate sheet into a vacuum chamber;
- forming a recording layer on said substrate sheet by sputtering in said vacuum chamber;
- preparing a transparent organic resin protective sheet having a softening point less than or equal to the softening point of said heat-resistant organic resin substrate sheet;
- taking said protective sheet into said vacuum chamber;
- thermally pressing said protective sheet against said recording layer in said vacuum chamber to form a thermally laminated sheet mass;
- taking said thermally laminated sheet mass out of said vacuum chamber; and
- cutting said thermally laminated sheet mass into a prescribed form.
- 2. The method according to claim 1, wherein said heat-resistant organic resin substrate sheet is prepared from one of polyimide resins and fluorine-contained resins.
- 3. The method according to claim 1, wherein said recording layer is prepared wholly or mainly from tellurium.
- 4. The method according to claim 1, wherein said transparent organic resin protective sheet is prepared from one of polyester resins and fluorine-contained resins.
