There is disclosed a crosstalk removal apparatus in which a main track, one adjacent track, and the other adjacent track in a disk with the tracks formed therein are irradiated with light beams at predetermined intervals in a tangent direction by a pickup. A CTC unit uses delay amounts of respective sample value series corresponding to a reproduction signal of the main track and those of the adjacent tracks to correct delays, and outputs a CTC output signal from which a crosstalk component is removed. A wobble signal detector detects wobble signals of the respective tracks based on a push-pull output of the disk, and a delay circuit controller obtains optimum delay amounts based on a phase relation of the respective wobble signals and sets the delay amounts in the CTC unit.
