摘要： An optical recoding medium is provided to prevent interference and crosstalk of a signal by determining a maximum distance from the surface of the recording medium to lowermost recording layers, and minimizing an interval between recording layers. The sin theta multiplied by n cov indicating the refractive index of a cover layer is NA representing the aperture ratio of a seal lens(21), thereby an incident angle theta is arcsin(NA/n cov). A bottom surface(32) of a recording medium is formed at the lower part of lowermost recording layers(31) to prevent damage to the recording layers of the recording medium. The aperture ratio of the seal lens is 1.6 to 1.85, and the refractive index of the cover layer is 1.83 to 2.
