[Means for solving problems]
The above-mentioned problem is (1) of the present invention, "in an optical disk reading device using a hemispherical or ultra-hemispherical solid immersion lens having a numerical aperture of 1 or more, a material transparent to reading light and a surface on the reading side. The read-only medium, wherein information is recorded due to the unevenness of the lens, and (2) the read-out according to the above item (1), wherein the recording bit is concave with respect to the surroundings. Dedicated medium ”, (3)“ Read-only medium according to item (1) above, wherein the recording bit is convex with respect to the periphery ”, (4)“ Hemisphere having a numerical aperture of 1 or more. A read-only medium characterized by a material that is transparent to the reading light and information is recorded through holes through which data penetrates in an optical disk reading device using a solid-state and ultra-hemispherical solid immersion lens. " (5) "The read-only medium according to item (2) or (3) above, wherein a light absorbing layer is provided on a surface opposite to the incident side of the reading light", (6) "Light. The read-only medium according to item (5), which is characterized in that a heat-dissipating layer is provided in contact with the absorption layer, and (7), a light absorption mechanism for stopping light that has passed through the read-only medium is provided. This is achieved by the optical disk reading device for reading the read-only medium according to any one of the items (1) to (6).
