ABSTRACT:
An optical information recording and/or reproducing apparatus is provided wherein an information recording medium and an optical head are moved relatively in a track direction in a reciprocal manner to record optical information on the information recording medium and/or reproducing optical information recorded on the information recording medium. The apparatus is arranged such that when a defect is formed on a stopping position of the relative movement of the optical information recording medium and the optical head, the optical information recording medium or the optical head is stopped at a deviated position from the predetermined stopping position; and the deviated distance of the relative movement of the optical information recording medium and the optical head is corrected when relative movement between the optical information recording medium and the optical head is resumed in an opposite direction to the previous relative movement direction.
