Providing an optically information-recording medium which promoting the adhesiveness between each layer and including the property of stably recording regeneration. Applying the recording layer 16, binder layer or adhesive layer 20, and cover layer 22 in order on the substrate 12, which the track pitch is 300-600 nm, the trench depth is 40~150 nm, applying the information of recording regeneration with laser of 500 nm less, and having the central pore 24 on the dish optically information-recording medium. Furthermore, at lease one region of the inner or outer neighbor of the substrate 12 and cover layer 22 bind together by using the binding layer or adhesive layer 22, and the length's maximum of the diameter direction of the said binding area is up to 0.4 mm on the optically information-recording medium. |
