Abstract

Device for the production of optical discs made up of the assembly of at least one substrate of a first category (101) and of at least one substrate of a second category (102), the device comprising a qualification station (3) for the qualification of substrates (10) into substrates of said first category (101) or into substrates of said second category (102) according to determined parameters. Related method and computer program product. The qualification of substrates (10) according to determined parameters, for instance according to the number of rejected substrates (10, 101, 102) of each type, allows an optimisation of the device's productivity, allowing in particular a reduction of the rejected material.
