<p>An optical disk comprises a first member (111), which has a disk-shaped first transmission substrate (101), a reflecting layer (103) provided on the first transmission substrate (101), and a protective layer (105) provided on the reflecting layer (103), for recording the desired information, an adhesive layer (107) having a first surface and a second surface bonded to the protective layer (105), and a second member (112) having at least a second transmission substrate (102) bonded to the first surface of the adhesive layer (107), wherein the thickness of the optical disk is 1.19 mm or more and the degree of a deviation in said optical disk rotating at a specific rotation speed is within +/- 0.3 DEG . <IMAGE> <IMAGE></p> |
