The reproduction characteristics, particularly the C/N ratio of a reproduced signal of an optical recording medium are deteriorated by an unevenness or deformation of an optical recording layer due to a convex or concave configuration of an underlying guide means is formed on the surface of the substrate. This deterioration can be prevented by disposing a planalization layer under the recording layer but the planalization layer lowers the efficiency of the servo tracking. This lowering of servo tracking efficiency is prevented by insertion of a dielectric layer between the planalization layer and the guides.

Les caractéristiques de reproduction d'un signal reproduit sur un support d'enregistrement optique, notamment le rapport porteuse/bruit, sont détériorées par la présence d'inégalités ou de déformations dans la couche d'enregistrement du fait de la convexité ou de la concavité d'un guide sous-jacent. L'interposition d'une couche d'aplanissement sous la couche d'enregistrement permet de supprimer cette détérioration, mais la couche d'aplanissement diminue l'efficacité au niveau du suivi de piste. La diminution de l'efficacité au niveau du suivi de piste peut être prévenue par l'insertion d'une couche diélectrique entre la couche d'aplanissement et les guides.
