Summary: | A recording medium includes a transparent substrate (14); a crystalline phase-change layer (12) provided over the transparent substrate; a dielectric layer (16) provided over the phase-change layer; a metallic reflector layer (18) provided over the dielectric layer; and the crystalline phase-change layer having a thickness and phase-change material selected so that data can be recorded in it on a first write, but on second or subsequent writes the written data results in at least a 50% increase in data jitter. |
