ABSTRACT:
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.
