摘要： PROBLEM TO BE SOLVED: To provide an optical information recording medium that can protect a transparent protective layer, has a projecting part for reducing a load on a motor upon rotation and can provide a greater force to hold a disk. SOLUTION: The optical information recording medium has a signal substrate, a signal recording layer, and the transparent protective layer formed on the signal recording layer, and is the optical information recording medium that has a center hole. Information is recorded or reproduced by radiating light on the signal recording layer through the transparent protective layer, and a holding area is formed between the center hole and a signal area matching an area where the signal recording layer is formed, and the projecting part that projects ahead of the transparent protective layer is formed on the light-incident face side of the area which is sandwiched by the center hole and the holding area.

摘要： PROBLEM TO BE SOLVED: To provide an optical information recording medium having a protruded part protecting a transparent protective layer, reducing the load on a motor during rotation, and achieving larger disk clamping force. SOLUTION: The optical information recording medium has a signal substrate, a signal recording layer, and a transparent protective layer having the thickness of 10 μ m to 200 μm and disposed over the signal recording layer, and has a center hole having the diameter of 15 mm. Information is recorded/reproduced by irradiation of the signal recording layer with light through the transparent protective layer. The optical information recording medium includes a clamping area in an area between a signal area corresponding to the area where the signal recording layer is formed and the center hole. The transparent protective layer is formed so as to cover the signal area of the substrate, the clamping area, and an area at the inner side thereof. A protruded part is formed by sticking a member different from that of the signal substrate on the surface of the transparent protective layer in an area having the diameter of 17.5 to 22.0 mm interposed between the center hole and the clamping area.
