APPARATUS FOR REPRODUCING INFORMATION

摘要

This apparatus reproduces data from a recording medium by a partial response method and decodes data by use of a shift register by the Viterbi decoding technique. The shift register has flip-flops Daj which latch data and are connected in series, and the XOR gates (31a to 31d) connected between the flip-flops Daj and used as operating means for calculating the exclusive disjunction of the outputs of the flip-flops so that CRC operation is executed.
