[origin: WO2007131672A1] The invention relates to a method for joining at least two substrate discs that have an inner hole, to form a data carrier. Said method comprises the following steps: placing of at least two substrate discs, which lie on top of one another and have a liquid adhesive sandwiched therebetween, on a stationary receiving pin; and generation of a negative pressure in the vicinity of the inner hole, in order to draw the liquid adhesive towards the inner hole.
