Abstract
An adaptive equalizer includes a recording density detector for calculating a recording density reference value by obtaining the track radius using input track information, a reference tap coefficient storage portion for storing the reference tap coefficient obtained according to the channel impulse response at the lowest density position, a tap coefficient controller for obtaining a tap coefficient according to the recording density using the recording density reference value on the basis of the reference tap coefficient stored in the reference tap coefficient storage portion, and a waveform equalizer for eliminating the interference of the signal adjacent to the input reproducing digital signal using the tap coefficient obtained from the tap coefficient controller, to output the reproducing information signal. Therefore, the recording density is assumed by the track information of the reproduced data and the reproduction signal is adaptively waveform-equalized, so that high-speed real-time processing is possible and the circuit construction can be simplified.
