PURPOSE:To shorten the time to remove an optical disk base plate and to strengthen the adsorption force required to remove the plate in the method and apparatus for removing the optical disk base plate. CONSTITUTION:A robot moves a handling base plate 10 close to an optical disk base plate P so that the two plates face each other. Compressed air A is fed between a movable mold 1 and the optical disk base plate P, and an ejector pin 2 presses the optical disk base plate P to both seal rings 11, 12 of the handling base plate 10. Thus both seal rings 11, 12 contact the optical disk base plate P excluding its signal recording area Pf. The air Al in the space corresponding to the signal recording area Pf, that is a space S, is discharged from a discharge port 14, so that the handling base plate 10 adsorbs the optical disk base plate P. In this state, a robot moves the handling base plate 10 to the right to remove the optical disk plate P from the movable mold 1. |
