OPTICAL DISK FORMAT FOR DIRECT WRITING MATERIALS ON A SUBSTRATE

摘要

A direct write carrier, system and method include an optical assembly (11) configured to direct a writing laser (16) and a tracking laser (22). A carrier (12) has a material layer (18) and a tracking layer (14). The carrier is moveable relative to the optical assembly such that when the material layer is energized by the writing laser, direct writing is provided to a surface below the carrier. The tracking layer includes readable data which is employed to control one of the optical assembly and a position of the carrier.
