Zusammenfassung: | The present invention provides an apparatus for optical disc spin-coating that prevents leakage of a photocurable resin due to a capillary phenomenon by controlling a contact area between a cap and a disc so that contamination of the disc and manufacturing errors do not occur. Furthermore, the apparatus of the present invention can manufacture an optical disc having a central portion which is not contaminated by a photocurable resin and in which bubbles are not generated. In addition, the apparatus may further include a vacuum hole formed in the turntable, which can be opened and closed independently from the opening and closing of a vacuum hole formed in the central axis of the turntable, to prevent the lifting of the optical disc when the cap is removed. As a result, operability and the manufacturing efficiency of the apparatus can be increased significantly. |
