Abstract
Se provee un medio de informacion optica (20) para la grabacion que se puede borrar por medio de un haz de luz láser. Un sustrato (1) soporta una pila (2) de capas con una capa de grabacion de cambio de fase (5) entre una primera capa dieléctrica y una segunda capa dieléctrica (6). Una capa de absorcion de luz (7) se encuentra presente proxima a la capa de grabacion (5) y está hecha de un compuesto de la formula QRx en la cual Q es el elemento Si, Ge, Ti, Zr, Hf, Nb o Ta, R es el elemento O o N y 0<x<2,5 para lograr que 0,8 <Ac / Aa < 1.50, en la cual Ac y Aa son las cantidades respectivas de luz láser absorbida en la capa de grabacion (5) en el estado cristalino y el estado amorfo en la longitud de onda de luz láser seleccionada de un rango de 350-450 nm. Así se obtiene una alta velocidad de transferencia de datos y la baja perturbacion de datos en este rango de longitud de onda corta sintonizando a x en un valor optimo durante la fabricacion del medio de informacion optico.
