ABSTRACT:
An apparatus for use in a digital recording/reproducing system includes a first comparator for receiving a reproduced analog signal, comparing the voltage level thereof with a first reference voltage of a predetermined level, and outputting a first comparison result; a switch for switching on and off a connection with the reproduced analog signal in accordance with the first comparison result; a reference voltage adjuster for charging or discharging a charge element in accordance with the on/off state of the switch in the switch, and adjusting a second reference voltage of a predetermined level for data detection; a second comparator for receiving a reproduced analog signal, comparing the voltage level thereof with the second reference voltage adjusted in the reference voltage adjuster, and outputting a second comparison result; and a restorer for receiving the second comparison result, synchronizing the received result with a clock signal, and restoring the synchronized signal into a digital signal. A data detection method reduces the probability of error generation due to time-axis motion of signals, by adjusting the reference voltage in accordance with input signals.
