Abstract

Description d'un matériau d'enregistrement capable de fournir un signal reproduit ayant un rapport S/N amélioré. Ce matériau d'enregistrement comprend un substrat en plastique sur lequel est formée une pellicule d'enregistrement dont la forme ou la propriété varie en fonction de rayons de traitement, et une couche polymère à surface lisse composée d'un polymère non-photosensible et disposée entre le substrat en plastique et la pellicule d'enregistrement.Description of a recording material capable of providing a reproduced signal having an improved S / N ratio. This recording material comprises a plastic substrate on which is formed a recording film whose shape or property varies depending on processing radii, and a smooth-surface polymer layer composed of a non-photosensitive polymer and arranged between the plastic substrate and the recording film.
