Eccentricity adjusting apparatus for disc for data recording and/or reproduction and eccentricity adjusting method using it

摘要

Eccentric Eccentric calibration device and calibration method disclosed information of the disk for recording and reproducing track the angle of rotation of the disc , Placing the disk up to a position offset caused by the rotational position detecting means is detected , a rotational position detection means for finding a rotation angle of the disk when the tracking error caused by the eccentricity at the maximum rotation toward the axis of rotation of the disk, the pushing means comprising a pushing hayeoseo reduce the amount of eccentricity is moved , so as to correct the eccentric disk at the time of assembly . According to the offset correction apparatus and calibration method , the assembly of the disc to be able to correct fully the pre- offset , and write information to the disk, it can be significantly reduced since the possibility of errors caused by eccentricity in to play .
