Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical disk unit and a disk tilting detection method for detecting disk tilting without using a private tilting sensor.  <P>SOLUTION: A tilting control circuit 69 detects tilting of a pickup 65 with respect to warping of a disk based on a focus control signal obtained from the reflected light of an optical beam projected to a disk, and outputs a correction signal Tc so as to make an objective lens 70 follow a disk recording surface. Based on a reproducing signal from the reflected light of the optical beam projected to the disk, a jitter measuring circuit 42 detects the minimum value of the jitter of this reproducing signal and outputs a correction signal so as to make the objective lens 70 follow the disk recording surface according to this minimum value. A switching circuit 44 determines whether data are recorded in the disk, selects the tilting control circuit 69 outputting the correction signal Tc when the data are not recorded, and selects the jitter measuring circuit 42 for outputting a correction signal Jc when the data are recorded.  <P>COPYRIGHT: (C)2004,JPO
