摘要： PROBLEM TO BE SOLVED: To provide an optical disk whose disk substrate on the information reading surface side has the prescribed thickness and to provide a method for manufacturing the optical disk. SOLUTION: This optical disk comprises the first disk substrate 101 and the second disk substrate 102. The substrate 101 has a cylindrical projection 101b formed in the peripheral part of a center hole 101a on the side of the substrate 102 laminating surface which is formed as the information recording surface. The substrate 102 is formed by dropping a liquid substrate material in a ring shape along the peripheral part of the projection 101b and hardening the substrate material spread on the substrate 102 laminating surface by lowering the pressure of the outer peripheral part nearest to the dropped substrate material.

摘要： PROBLEM TO BE SOLVED: To easily form a spacer later of prescribed thickness by providing a projection part of a prescribed height on a disk substrate, and forming the spacer layer having the same hight as the projection part. SOLUTION: An optical disk 10 is constituted so that a step difference 12 with the prescribed height is provided on the outer peripheral part of the substrate 11, and a first rugged pattern based on a first recording signal is formed on a prescribed surface 11A in the step difference 12, and a first reflection film layer 13 with a low reflectance of light is formed on the surface. Further, the spacer layer 14 of resin having high light transmissivity is formed on the reflection film layer 13, and a second rugged pattern based on a second recording signal is formed on its upper surface 14A, and further, a second reflection film layer 15 with a high reflectance of light is formed on the upper surface 14A to be covered by a protection film layer 16. The optical disk 10 formed in such a manner facilitates the formation of the spacer layer 14 having the thickness capable of preventing interference of reflection light by providing the step difference 12 of the height (t) on the substrate 11 and laminating and forming the first rugged pattern, the first reflection film layer 13 and the spacer 14 within the height (t) by the step difference 12.

摘要： PROBLEM TO BE SOLVED: To reduce eccentricity, thickness balance or warpage by sticking a first disk substrate with a second disk substrate based on a first sticking mark and a second sticking mark. SOLUTION: After disk substrates 21AX and 22AX are molded, first and second reflection film layers 21B and 22B are formed on the rugged pattern surfaces 21A and 22A of the disk substrates 21AX and 22AX respectively. Then, the disk substrates 21 and 22 are stuck each other by an adhesive 23 making signal recording surfaces 21c and 22c sides sticking surfaces so that respective answering marks of marks 21E1 -21E4 and marks 22E2 -22E4 formed on the disk substrates 21 and 22 match with each other. In such a case, since the marks 21E1 -21E4 and the marks 22E1 -22E4 are recorded, and they are formed on a stamper, the complexity that the marks are formed whenever the disk substrates 21 and 22 are formed is evaded.
