OPTICAL DISC LABEL PRINTING USING OPTICAL PICKUP UNIT WITH MULTIPLE FOCI

摘要

The present invention provides a system for recording an image onto a label layer of an optical disc. The optical disc also includes a data layer on which a plurality of predetermined address codes is marked. The system essentially includes a multi-focal lens module for dividing a laser beam emitted by an optical pick-up unit into a first beam portion and a second beam portion. The first beam portion is focused on the data layer to locate a first position by retrieving the predetermined address codes. The second beam portion is focused on the label layer to record the image at a second position opposite to the first position.
