摘要： An ADIP (address in pre-groove) signal detection circuit is capable of correctly and quickly detecting discontinuous points in a wobble signal, and has a simple configuration in a wobble detection system of an optical disc device such as a DVD+R/RW, and an ADIP signal detection method thereof. The ADIP signal detection circuit performing the ADIP signal detection method includes one or two window comparators, two edge detection circuits each consisting of an exclusive OR circuit and an AND circuit, and two discontinuous point determination circuits each consisting of a flip-flop and a counter. Therefore, the ADIP signal detection circuit has a simple configuration so that it can be easily implemented. Also, since the ADIP signal detection circuit has a fast operation speed, the ADIP signal detection circuit detects discontinuous points correctly and quickly.
