Abstract
A sheet used as a spacer layer is made of photo-curing organic material and thermoplastic organic material, a stamper is pressed on the sheet, and light irradiating is performed after the stamper is stripped.
Claims6
A production apparatus of a recording medium that forms a spacer layer on a substrate on which a recording film is formed, comprising:
- a stamper for transferring a pattern on a sheet used as a spacer layer;
- a heating part that heats the sheet for transferring the pattern by the stamper;
- a pressure part that presses the sheet for transferring the pattern by the stamper;
- a stripping part that strips the stamper from the sheet;
- and
- a light irradiating part for irradiating light on the sheet, wherein the stripping part is between the pressure part and the light irradiating part.
