摘要： According to one embodiment, when a focus servo goes off and the distance between an objective lens and a recording layer of an optical disc does not coincide with a focal length of the objective lens, a control voltage or current corresponding to an optical disc wobble stored in a memory is superimposed on a control voltage or current supplied to a driving mechanism to move an objective lens along an optical axis for re-focusing, and the superimposed voltage or current is supplied to the driving mechanism. Therefore, pull-in of a focus servo for re-focusing is possible in a short time.
