摘要: Some characteristics of reversible phase‐change optical data storage in TeSeSb alloys are given. High signal‐to‐noise ratios reached at low recording energies. Upon passage an oblong scanning laser spot, erasure occurs by growth from the crystalline surroundings amorphous effects velocities up to 5 cm/s. Isothermal transformation appears be dominated phase separation and diffusion processes. The tradeoff between long‐term stability time varies with alloy composition and, for some alloys, attractive properties respect retention times found.
