Optical information recording medium, method of manufacturing the same, and sputtering target |
摘要 |
An optical information recording medium (9) of the present invention is an optical information recording medium including: N information layers, where N is a natural number of 2 or more; and an intermediate layer for separating the N information layers optically from each other. With the N information layers being referred to as a first information layer (10) to an N-th information layer (7) sequentially from an optical beam incident side, a first information layer (10) corresponding to an L-th information layer included in the N information layers includes a recording layer (104) on which information can be recorded by irradiation with an optical beam, a reflective layer (108), and a transmittance adjusting layer (109) in this order from the optical beam incident side, where L is an at least one natural number that satisfies 1≰L≰N−1. The transmittance adjusting layer (109) contains tungsten (W) and oxygen (O).
