Abstract: Disclosed herein are a high-density recording medium and a method and apparatus for controlling data playback thereof. Playback control information, such as channel bit length information, is recorded in a burst cutting area (BCA) of a high-density optical disc in a wobble type. When the high-density optical disc is reproduced, the playback control information is detected in a push-pull signal detection mode and the optimum data playback operation corresponding to the recording capacity of the optical disc is performed on the basis of the detected playback control information. Alternatively, bit error rates (BERs) are calculated while a plurality of predetermined bit detection modes are sequentially performed, one of the bit detection modes corresponding to the smallest one of the calculated BERs is selected and the data playback operation is performed in the selected bit detection mode.
