Title: Optical disk
Inventor: HANZAWA SHINICHI
IPC: G11B7/24
Filed: 2000-06-06
Abstract: PROBLEM TO BE SOLVED: To enhance the durability of a light transmitting layer, which is formed on the signal recording surface of a substrate of an optical disk where recording/reproducing is carried out by irradiating with laser beam from the light transmitting layer side, and makes the light transmitting layer thin, uniform in thickness and excellent in quality. SOLUTION: The substrate 1 has a disk-like shape having diameter defined as D1 and a center hole 1a of diameter defined as D2 and around 1.2 mm thickness. A signal recording layer 2 is formed on the substrate 1 and a transparent sheet 3 is further laminated on the layer 2. The sheet 3 has a ring-like shape having diameter defined as d1 and a center hole of diameter defined as d2 so that d1 is made smaller than D1 and d2 is made larger than D2. When the sheet 3 is stuck onto the substrate 1 to cover the layer 2, margins are generated between the outer peripheral end of the substrate 1 and that of the sheet 3 and between the peripheral end of the hole 1a and the inner peripheral end of the sheet 3.  Even when external force is given to the substrate 1 during handling, the change of the state of the sheet 3 such as peeling off is hardly caused since the sheet 3 is isolated from the substrate 1 by the margins.
