ABSTRACT:
An optical disc recording/reproducing apparatus according to the present invention determines the state of recording of an optical disc on the basis of the detection period of longest pits recorded on the optical disc wherein the period is changed with the acceleration of the rotation of the optical disc until a predetermined rotation speed is achieved. This enables rapidly determining whether the optical disc is unrecorded disc or a recorded disc.
