Embodiment Construction

[0033] First, refer to figure 1 A preferred embodiment of an optical disc manufacturing device of the present invention corresponding to an optical disc manufacturing method according to the present invention is described, wherein figure 1 A rough layout of the optical disc manufacturing facility is shown.

[0034] figure 1 In, reference numeral 1 denotes a molding machine (manufactured by Kabushiki Kaisha MEIKI Co., Ltd.) capable of simultaneously forming two disk substrates having different information recorded on each surface thereof.

[0035] The mobile placement device 2 comprises a mobile placement arm and its drive unit. The moving setter 2 simultaneously sucks, holds and accepts two disk substrates delivered from the molding machine 1, rotates them in a substantially vertical direction and sets them on a cooling mechanism 3 which will be described in detail later.

[0036] Since the temperature of each molded disc substrate is high, the cooling mechanism 3 is used t...

Abstract

A molding machine 1 which molds two sheets of disc substrates on which the information is recorded simultaneously, a cooling mechanism 3 for cooling each of the disc substrates, first movably mounting means 2 for movably mounting the disc substrate from the molding machine onto the cooling mechanism, and a second movably mounting means 4 for mounting each of the disc substrates onto a receiving portion of the turn table 5 are provided. In addition, a film forming device 8 for receiving sequentially each of the disc substrates from this movably mounting means 6 and forming a reflective film on one of the surfaces of each of the received disc substrates on which the information is recorded; a turn table 10 having a plurality of receiving portions on which the disc substrates are mounted and which rotates intermittently through each constant angle; a reversing mechanism 11 which reverses 180 degrees each of the disc substrates; and an overlapping mechanism for overlapping the reversed disc substrates over the other disc substrates are provided. Furthermore, spinners 15, 16 for rotating the overlapped two sheets of disc substrates and a curing device 23 which radiates ultra-violet rays onto the disc substrates which are rotated by the spinners to cure the liquid adhesive. According to the above-described structure, an optical disc which is compact, is fast in a production speed, and has a high quality can be achieved.

Description

technical field [0001] The present invention relates to a manufacturing technique of an optical disc capable of optically reading recorded information and bonding two disc substrates. Background technique [0002] The technology of increasing the recording capacity by means of an optical disc has been produced and widely promoted. In addition, the recording capacity of optical discs tends to be denser. For example, an optical disc called DVD-9 having a recording capacity of 8.5 gigabytes and recording on both surfaces of each layer of a dual-layer structure has been produced. A method of manufacturing an optical disc of the above-mentioned type is to form two substrates on which information different from each other is recorded by two molding machines, and form reflections on their corresponding recording surfaces by two sputtering devices. Reflective films with different efficiencies are used, and the two substrates are bonded together with their recording surfaces facing...
