Apparatus for making multi-layer optical discs

摘要

A method and apparatus for making multiple layer optical discs is applied to separate the base plate from the mold plate. The apparatus includes a first adhesive ending groove, a mold plate, a sealing member and an air-blowing axle. The adhesive does not cover the area around the first and second openings and the first and second adhesive ending grooves, so an enclosed cavity is formed between the first and second openings. The air-blowing axle passes through the second opening and encloses the cavity but leaves injestion ports in the cavity so that air can be injected into the cavity for separating the base plate and the mold plate while the second recording layer and the adhesive layer adhere to the base plate.
