Abstract
A recordable element with improved performance, and a method of making such element is disclosed. The recordable element includes a substrate and an optical recording layer deposited on the substrate, wherein the optical recording layer is formed of Te.sub.a Ge.sub.b C.sub.c H.sub.d O.sub.e where a, b, c, d, and e are atomic percents such that a+b+c+d+e=100, and wherein 10<a<40, 10<b<60, 5<c<35, and 15<(c+d)<65 and e.gtoreq.0; a metal layer over the optical recording layer; and the recording element having its properties changed by heat treatment for a time and temperature selected so as to significantly improve jitter, window margin, reflectivity, and recording sensitivity performance.
