Abstract

This paper presents the results of two studies on long-term readout of organic optical recording media: (a) bit error measurements from digital data tracks read 10⁶-10⁷ times from a rotating disk versus IR read power and (b) simulations of a very large number of readouts (10⁸-10⁹) using a pulsed IR read source to interrogate stationary pits. The second technique is used to provide data at a number of read cycles too time consuming for the first method, thus providing an efficient means to evaluate novel media.
