Abstract
A signal processing apparatus capable of reducing burst error generation, and a highly reliable data recording/reproducing apparatus using this signal processing apparatus. This signal processing apparatus has a simple error detection/correction circuit provided just before a modulated code demodulator, thereby correcting error of a pattern easy to occur in a maximum likelihood decoder. The simple error detection/correction circuit is an error detection/correction circuit using a linear error correction code, for example, an error correction code (CRCC) formed of a cyclic code. Thus the number of burst errors after the modulated code demodulator can be decreased.
