    摘要： An apparatus includes a multiple detecting unit having n detectors, and a controller which selects one of the n detectors and controls the selected detector to output a binary signal. In the apparatus, a plurality of detectors are used to detect a signal read from an optical storage medium, and the optimum detector is selected in consideration of a quality of the signal and detection conditions, thereby increasing the efficiency of a signal reproduction. The apparatus can selectively compensate for disturbance of a signal where data from the optical storage medium is reproduced. The apparatus may control a run length of the signal to be 3T.
