摘要： An optical disk has a recording substrate and a support base. The substrate has a first light incident plane and a first bonding surface on both sides thereof, data being to be recorded in the substrate via the first plane. The base is constituted by at least one component and has a second light incident plane and a second bonding surface on both sides thereof, the substrate and the base being bonded to each other via the bonding surfaces. The substrate is constituted by components that are at least a first substrate, a recording layer and a reflective layer, the first substrate having a first substrate surface and a second substrate surface on both sides thereof, the first plane being provided on the first substrate surface, the recording layer being provided on the second substrate surface, the reflective layer made of at least silver and having a first layer surface and a second layer surface on both sides thereof, the first layer surface being provided on the recording layer as the first layer surface faces with the second substrate surface via the recording layer. At least one component that exists between the second plane of the support base and the second layer surface of the reflective layer exhibits a transmittancy in the range from 0% to 25% when the optical disk is exposed to light having a wavelength of 350 nm through the second light incident plane.
