Abstract

Un tipo de disco en un dispositivo de reproduccion se determina exactamente antes de la reproduccion del dato. Para determinar si el tipo de disco es Disco Compacto (CD) o Disco de Video Digital (DVD), se examina un paso de la pista en el disco, mientras que la diferencia entre la Sola Capa de DVD y la Capa Doble de DVD se basa en los valores de reflectancia del disco. Cuando el dipo de disco determinado de esta manera es incorrecto, se lleva a cabo una operacion para calcular el tipo de disco correcto basándose en la posibilidad más elevada de tipo de disco después de la decision inicial (incorrecta). El proceso se lleva a cabo hasta que se idéntica el tipo de disco correcto, o el disco de determina que es inutilizable.
