Abstract
A method and apparatus for joining at least two substrates together, especially to form an optical data carrier, are provided. Substrates are disposed in a spaced-apart manner between two plates that are disposed opposite from, and are movable relative to, one another. At least one of the plates is connected to a flexible membrane. At least the plate to which the flexible membrane is connected is moved in such a way that a pressure difference is produced on opposite sides of the membrane.
