Apparatus for and method of manufacturing an optical disc

A method of manufacturing an optical disc by which a disc-shaped stamper stuck on the upper surface of a disc-shaped substrate with a resin layer interposed therebetween so as to be concentric with said disc-shaped substrate and having an outer diameter larger than the outer diameter of said disc-shaped substrate is stripped off from said disc-shaped substrate, said method comprising the steps of:

• causing the substrate having said stamper stuck thereon to be attracted to and held on the circular surface of a table contacting with the underside of said disc-shaped substrate to thereby attract and hold said substrate and having as the upper surface thereof a circular surface having an outer diameter equal to or smaller than that of said disc-shaped substrate;
• bringing rollers disposed at locations equidistant from the center of said circular surface of said table and at regular intervals around said table, contacting with an area which is the surface of said stamper opposed to said disc-shaped substrate and protrudes from the area stuck on said disc-shaped substrate, and capable of rolling relative to the contacting surface of said stamper into contact with said protruding area;
• and
• rotating said table relative to said rollers with the center of said circular surface of said table as a rotation center and at the same time, elevating said rollers relative to said circular surface of said table in a direction perpendicular to said circular surface.
