| 摘要 |
An optical recording medium including a substrate, a bottom protective layer located overlying the substrate, an optical recording layer located overlying the bottom protective layer, a top protective layer located overlying the optical recording layer, an intermediate layer located overlying the top protective layer, comprising at least one element (M) selected from the group consisting of Ti, Nb and Ta, and carbon, an optical reflective layer comprising Ag in an amount not less than 95 atomic %, located overlying the intermediate layer. The optical recording medium is recordable even in at least one of the following recording conditions (1) to (3): (1) when a recording time for a shortest recording mark is not greater than 34 ns; (2) when a recording time of a channel bit length is not greater than 11 ns; and (3) when a recording linear velocity is not less than 11 m/s.
