发明名称 Optical disc drive
摘要 An optical disc drive which can at least read out data from an optical disc is disclosed. The optical disc drive comprises a rotational drive mechanism for rotating the loaded optical disc at a predetermined rotation speed which is one of multiple rotation speed levels; an optical pick-up for reading out data from the optical disc which is rotated by the rotational drive mechanism; a judgement device for making a judgement as to whether the data has been properly read out from a predetermined portion of the optical disc; and a retry control device for lowering the rotation speed of the optical disc from the predetermined rotation speed when the judgement device has judged that the data has not been properly read out from the portion of the optical disc, and then for retrying to read out the data from the same portion of the optical disc rotating at the lowered rotation speed. <IMAGE>
