A method and apparatus for making multiple layer optical discs is applied to separate the base plate from the mold plate. The base plate is formed with a first opening, an empty zone and a data zone having a first recording layer. The apparatus includes a first adhesive ending groove, a mold plate, a sealing member and an air-blowing axle. The first adhesive-ending groove is formed on the empty zone of the base plate. The mold plate, movably pressed on the base plate, includes a main body, a second opening, a second adhesive ending groove, a second recording layer and an adhesive layer. The second opening is located on the main body at a position corresponding to the first opening of the base plate. The second adhesive-ending groove is located on the main body at a position corresponding to the first adhesive-ending groove of the base plate. 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 sealing member is mounted on the outer portion of the first opening. The air-blowing axle passes through the second opening and encloses the cavity but leaves injection 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.
