PURPOSE:To suppress the shrinking in curing of a resin film and to prolong the life of an optical recording medium without impairing the functions thereof by compounding a pigment with a UV curing resin. CONSTITUTION:This recording medium is constituted by forming germanium telluride as the optical recording film 12 on a polycarbonate substrate 11 and laminating the UV curing resin 13 compounded with a carbon black on the film 12. The UV curing resin liquid is prepd. by using a ball mill and compounding the acryl-base UV curing resin liquid, the carbon black and a dispersant. This liquid is coated on the optical recording film 12 by a spinner and UV rays are projected to the resin film to cure the resin. |
