PURPOSE: An encoding/decoding method for recording/reproducing high-density data and a system based on the method are provided to record/reproduce high-density data in/from a partial response maximum likelihood(PRML) channel. CONSTITUTION: An encoding/decoding system includes an encoder(100) for compressing input binary data, correcting an error in the data and modulating the data to encode the data, a signal generator(102) for generating a signal from the modulated data, a write equalizer(104) for previously compensating the signal output from the signal generator, and a storage unit(106) for storing the signal output from the read equalizer. The encoding/decoding system further includes a read equalizer(108) for processing a signal reproduced from the signal stored in the storage unit to facilitate detection of the reproduced signal, a detector(110) for detecting a signal from the signal output from the read equalizer in a manner that error probability is minimized, and a decoder(112) for decoding the signal output from the detector.
