A disc reproducing apparatus comprising a means for reproducing data recorded in a disc, a means for making a decision as to whether the reproduced data are proper or not, a means for detecting a face-down state of the disc in response to the result of the decision, and a means for controlling the driving of the disc in response to the result of the detection. When a disc (DVD) loaded in a normal state is rotated clockwise, the point of reproduction is gradually shifted toward the outermost of the disc. However, when a disc loaded in a face-down state is rotated, the point of reproduction is shifted toward the innermost of the disc, so that the required continuity of addresses fails to be ensured. Thus, the face-down state of the loaded disc can be detected from the result of the decision indicating non-continuity of the addresses.
