Patent ID: 7778135

Claim:
An optical recording medium having a plurality of information recording faces, wherein when a first information recording face and an h-th information recording face are set from the side close to the surface of the optical recording medium (where h denotes an integer satisfying h≧2), reflectance of the surface is set as α 0 , reflectance of the first information recording face is set as α 1 , and reflectance of the h-th information recording face is set as αh, and transmittance from the surface to the first information recording face is set as t 1 , and transmittance from the (h−1)th information recording face to the h-th information recording face is set as th, ((α(h−1) 2 ×α(h−2))/(th 2 ×αh))<0.01 is satisfied.
