Abstract

An optical disk fabrication process utilizes a projection printing tool with a high power light source to directly print required pre-written information onto the recording med Specifically, the fabrication process has the following steps: (a)fabrication of a projection mask using existing photolithographic technologies; (b)coating of the disk substrate with the desire optical storage medium; and (c)laser projection printing of the desired pre-written information on the storage disk.
