Part of the CD and DVD disc manufacturing process
that uses a laser (which is modulated by the data to be stored on
the disc) to expose areas of a photo-resist layer on a glass disc,
where the final pits are required. These areas are then developed
and the photo resist layer metallized so that stampers can be grown
by electroforming using this metal layer. The stampers are then
used for molding CD and DVD discs.
