摘要： PROBLEM TO BE SOLVED: To easily manufacture an optical disk of a large capacity wherein recording and/or reproduction of information is performed by irradiating information signal parts with a laser beam from a side of a light transmission layer having a thin and uniform thickness. SOLUTION: A substrate formed with the information signal parts is prepared and after adhesive layers are formed on the information signal parts of this substrate by applying an adhesive or tacky adhesive thereon at an approximately uniform film thickness, a transparent plastic film is press-bonded onto the adhesive layers while the film is kept tense. The transparent plastic film previously formed with the adhesive layers by applying the adhesive or tacky adhesive at an approximately uniform film thickness may be press-bonded to the information signal parts of the substrate thereon while the transparent plastic film is kept tense. The base previously formed with the adhesive layers by applying the adhesive or tacky adhesive at the approximately uniform film thickness may be press-bonded to the information signal parts of the substrate thereon while the base is kept tense and thereafter the base is peeled and removed from the adhesive layers and the remaining adhesive layers are used as light transparent layers.

摘要： PROBLEM TO BE SOLVED: To make the focus error and noise of a low-frequency region of an optical disk lower by averting the formation of rubbing flaws in injection molding.
SOLUTION: A resin is injection molded by using molds mounted with an optical master disk formed with micro-ruggedness, by which an optical disk substrate is formed. In the injection molding, a buffer material is interposed between the molds and the optical master disk. The buffer material has a coefficient of friction below 0.2. The optical master disk consists of, for example, Si or glass. More particularly, the external diameter working of the optical master disk is performed by blowing powder thereto. The formation of the optical disk of a laminated structure by packing a UV curing resin between the molds mounted with the stamper, then irradiating the resin with UV rays to cure the UV curing resin is also possible.
