Optical recording medium and method for manufacturing the optical recording medium |
摘要 |
An optical recording medium including a substrate having guide groove thereon; a first protective layer located overlying the substrate; a recording layer located overlying the first protective layer; a second protective layer located overlying the recording layer; a third protective layer of from 2 to 9 nm thick located overlying the second protective layer and comprising Si in an amount not less than 35 atomic percent; and a reflection layer including Ag in an amount not less than 95% by weight. An overcoat layer having a glass transition temperature of from 90° C. to 180° C. is preferably formed overlying the reflection layer. A method for manufacturing the optical recording medium is also provided.
