ABSTRACT:
A transparent protective layer (106) having a thickness of 100 μm is formed of a resin film (100), a boundary layer (104) and an adhesive layer (103) on a signal recording layer (102). When nf, ni and na are the indices of refraction of the resin film (100), the boundary layer (104) and the adhesive layer (103), respectively, the relationship among nf, ni, and na satisfies any one of the following equation: na<ni≦nf; na>ni≧nf; na<nf≦ni; or na>nf≧ni, and the relationship among nf, ni, and na satisfies the following equation |nf−ni|<|nf−na|. At this time, a protrusion (111) and a scratch (110) are optically buried within the boundary layer (104), reducing scattering of laser beams and disturbance in the wave front which occur in these portions, and thereby, the error rate can be reduced.
