METHOD AND APPARATUS FOR DIRECT WRITING

摘要

A method of performing direct writing and an optical medium for performing direct writing are described. The medium comprises an acceptor substrate including a substrate layer, a reflective layer provided on the substrate layer. The medium further comprises a donor substrate including a substrate layer, an ablative layer provided on the substrate layer, and a transfer layer. The optical medium is arranged such that when the ablative layer is ablated by a beam of laser light, a portion of the transfer layer is transferred from the donor substrate to the acceptor substrate. The optical medium further comprises tracking and addressing means arranged to allow an optical drive to determine the position of a read/write laser on the medium.
