Abstract

We discuss the development of an optical disc recorder with an on-line storage capacity of 1010 bits. Recording is done by laser machining of micro-sized pits in a thin tellurium film allowing direct-read-after-writing (DRAW) of the information. The recording format maps each bit of information to a recorded pit. The tellurium is deposited on a clear plastic disc configured to be self-protecting and easily handled. A major program objective was to demonstrate the feasibility of an inexpensive recorder and disc.
