Abstract
An phase change optical medium compatible with a flying head can include a substrate, a reflective layer, a first dielectric layer, a phase change information carrying layer, a second dielectric layer and a lubricant layer. The structure and materials used both protect the phase change layer from mechanical damage due to impact and from information-altering heat generated by impact.
