Abstract
A mold is for molding DVD discs to be joined together, back-to-back, to make a single disc. The mold includes a movable moldhalf and a stationary moldhalf. On one of the half-molds an inserting block extends a small distance into the mold cavity, so that the central part of the cavity is thinner than the outer part. The inner part and the outer part correspond approximately to the outer information band and the inner portion of the disc which is grasped. The mold is preferably used in a method using first a lower compression force during resin injection and then an increased force.
