Abstract
A laser recording medium in which a metal recording layer is completely encapsulated between an intermediate layer of solvent-based plastic material and a protective layer of polymeric material formed on the recording layer in a vapor deposition process.
Claims4
A laser recording medium comprising:
- a transparent substrate;
- a layer of plastic material formed directly on said substrate;
- a layer of optical energy absorbing material formed on said layer of plastic material;
- a second layer of plastic material formed on said layer of energy absorbing material in a vapor deposition process wherein a hot reactive monomer vapor is condensed as a polymeric coating on said layer of optical energy absorbing material without substantially affecting the physical integrity of said layer of optical energy absorbing material or the layer of plastic material thereunder, said second layer of plastic material being formed over all surfaces of said laser recording medium.
