Abstract
A recording medium utilizing metal azides as an energy amplifying substance is disclosed. A photosensitive material comprises an energy absorptive dye and a metal azide dispersed in an inert binder. Low to moderate pulses of laser light cause the azide particles to react exothermally creating a void in the photosensitive material which can be read by an optical readout device.
