Embodiment 1
[0033] A Blue-ray Disc-RE substrate (1) with grooves and lands is prepared. The track pitch is 74 μm and the thickness is 1.1 mm. Plating a silver (Ag) reflective layer (2) with a thickness of 100nm on the substrate by magnetron sputtering, and then plating a silicon nitride (SiN) first interface layer (3) with a thickness of 8nm on the reflective layer , and then plate zinc sulfide-silicon oxide (ZnS-SiO) with a thickness of 8nm on the first interface layer 2) the first protective layer (4), and then respectively form a recording layer (5) with a thickness of 11nm on the protective layer, and then plate zinc sulfide-silicon oxide (ZnS-SiO2) with a thickness of 19nm on the recording layer. 2 ) the second protective layer (6), and a second interface layer (7) of silicon nitride (SiN) with a thickness of 30nm is plated on the second protective layer, the film structure diagram is as follows figure 1 shown. Finally, a light-transmitting film (8) with a thickness of 0.1 mm was s...
