Abstract
The present invention disclosed an optical disc drive determining apparatus. The optical disc drive determining apparatus includes an optical pick-up head, a signal processing module, and a discriminator. The optical pick-up head is for receiving a reflected signal from an optical disc. The signal processing module, coupled to the optical pick-up head, is for processing the reflected signal into a derived signal having a plurality of pulses. The discriminator, coupled to the signal processing module, is for analyzing widths of the pulses to determine a disc type of the optical disc.
