Abstract

Con el fin de identificar el tipo de medio de grabacion, se puede proporcionar un conmutador o alternativamente se puede definir una característica física tal como el espesor de la capa. Se puede monitorear los cambioss en la señal de enfoque con el tiempo o lo plausible de la reproduccion de señal. Se enfoca el haz de lectura.
