METHOD AND APPARATUS FOR DETECTING A KIND OF DISK IN A DIGITAL VIDEODISK PLAYER

摘要

The present invention relates to a disc discrimination apparatus and method for a digital video disc, which comprises an optical pickup unit 10 for performing optical pickup from a disc and converting an optical signal into an electrical signal for output, A focus error detection unit 20 for detecting a focus error signal from the focus error signal, a compensation unit 30 for outputting a compensation signal for compensating the focus error so as to perform focus servo, A comparator 40 for outputting a focus error (FOK) signal when the focus error signal is smaller than or equal to the reference signal, and a comparator 40 for comparing the detected time with the predetermined first and second reference times A microcomputer 50 for discriminating the type of the disc and generating a control signal for setting a reproduction mode according to the discriminated disc type, When the focus servo is performed by driving the optical pickup unit 10 to perform the focus servo by driving the optical pickup unit 10 according to the compensation signal provided from the microcomputer 30, the microcomputer 50 supplies the optical pickup unit 10 And a drive unit 60 for setting the mode to a mode according to the type of the disc.;Therefore, the present invention has the effect of enabling the reproduction to be smoothly performed by discriminating the type of the disc more quickly and promptly.
