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.

摘要： A method of controlling a servo in an optical disc device and a servo control device using the method, in which the servo control device controls a servo for printing on a label surface of an optical disc and includes an optical pickup unit, an error signal generation unit, and a control unit. The optical pickup unit outputs a plurality of signals corresponding to a position of an object lens in response to light reflected from the label surface. The error signal generation unit outputs an error signal by selecting or combining one or more of the plurality of signals. The control unit adjusts the position of the object lens in response to the error signal. Therefore, because the position of the object lens can be adjusted with an increased range, the spot size of a beam condensed by the object lens can be adjusted within an increased range, and a data recording time can be reduced. Moreover, data retention characteristics and recording quality can be improved.
