1. An apparatus for detecting a signal read from an optical storage medium, comprising:
a multiple detecting unit including n detectors;
a controller which selects one of the n detectors and converts the read signal into a binary signal using the selected detector;
and
a read signal quality measuring unit which provides information regarding a quality of the read signal, which is input to
the multiple detecting unit, to the controller, wherein the controller selects the one of the n detectors based on the information;
wherein the read signal quality measuring unit comprises a jitter detection unit which measures a jitter from a radio-frequency
(RF) signal read from the optical storage medium and transmits the measured jitter to the controller, wherein the controller
selects the one of the n detectors based on the measured jitter.
