Method and apparatus for discriminating a disc type

摘要

An apparatus and method therefor to discriminate a type of disc including a motor rotating a disc, a pickup detecting light reflected from the disc, and a system controller. The system controller performs a control process of enabling a focusing operation on the disc while stopping an operation of the motor in a disc type discrimination mode and discriminates the type of disc according to a result of detecting a time corresponding to a distance from a surface of the disc to a data recording layer of the disc using a light reflected during the focusing operation on the disc.
