摘要： Provided are an apparatus for attaching and detaching a cap for optical disc spin-coating that can be easily attached to and detached from the cap for covering a center hole of an optical disc by including a permanent magnet when contaminated by a photocurable resin, an apparatus for spin-coating including the same, and a method of manufacturing an optical disc using the apparatus for attaching and detaching a cap for optical disc spin-coating. By using the apparatus for attaching and detaching a cap for optical disc spin-coating, the cap can be easily attached to and detached from the optical disc before and after the spin coating even when the viscosity of the photocurable resin is high. In addition, the use of the apparatus for optical disc spin coating and the method of manufacturing the optical disc results in high manufacturing efficiency.

摘要： There is provided an apparatus for optical disc spin-coating, comprising a cap having a tapered protruding portion or a recess in its central lower portion; a turntable for rotation that has a tapered recess or protruding portion formed in an end of its central axis that is inserted into a center hole of an optical disc, wherein the tapered recess or protruding portion of the turntable is coupled with the tapered protruding portion or recess of the cap in a convexo-concave structure; and a vacuum hole formed in an optical disc support of the turntable. When the cap is eccentrically placed on the optical disc, the cap can be easily attached. In addition, the cap can be easily detached from the optical disc by using vacuum pressure. As a result, the operability and manufacturing efficiency can be increased.
