| 摘要 |
The invention comprises an improved optical recording medium and information record wherein the light sensitive layer comprises a tracking layer having one or more openings extending therethrough and an absorber layer overlying the tracking layer and the openings therein thereby forming first and second regions of the light sensitive layer having different reflectivities which can be used to provide radial tracking information. The method of the invention includes the steps of depositing a tracking layer onto a light reflective layer, forming one or more openings through the tracking layer and depositing an absorber layer over the tracking layer and into the openings therein. |
