摘要: A portion of a chalcogenide transformation film in less reflective phase responds to low energy laser beam writing pulse by transforming crystalline phase. marmem alloy, secured the bottom side film, longer erasing lower at same physically stressing only that portion. The physical stress back An optical reader interprets as digital logic "1", and "0".
