(EN) COPY-PROTECTED OPTICAL MEDIA AND METHOD OF MANUFACTURE THEREOF
(FR) SUPPORTS OPTIQUES PROTEGES CONTRE LA COPIE ET PROCEDE DE FABRICATION CORRESPONDANT
Abstract
(EN) A method for fabricating read-only copy protected optical medium comprising: a substrate (54) having information pits (18) and lands (16) thereon and a light sensitive material (56) placed at a position capable of altering the data reading during copying of the optical medium but permitting read of the underlying data in the reading of the optical medium.
(FR) Cette invention se rapporte à un procédé servant à fabriquer un support optique non inscriptible protégé contre la copie, qui comprend un matériau photosensible dans des positions capables de modifier la lecture des données pendant le copiage du support optique, tout en permettant la lecture des données sous-jacentes lors de la lecture de ce support optique.
