ABSTRACT:
Disclosed is a disc drive apparatus. The disc drive apparatus includes a rotational driving unit rotating a disc-shaped recording medium having a plurality of addresses recorded on an information recording surface of the disc-shaped recording medium; an optical pickup recording and/or reproducing an information signal on the information recording surface of the disc-shaped recording medium rotated by the rotational driving unit; and a control unit controlling rotation of the disc-shaped recording medium via the rotational driving unit. In the disc drive apparatus, the control unit carries out a disc constant velocity rotating processing that sets a predetermined address out of the plurality of addresses as a constant velocity rotation address and continuously reproduces the constant velocity rotation address using the optical pickup.
