PCT No. PCT/JP94/00330 Sec. 371 Date Nov. 1, 1994 Sec. 102(e) Date Nov. 1, 1994 PCT Filed Mar. 1, 1994 PCT Pub. No. WO94/20961 PCT Pub. Date Sep. 15, 1994The information reproducing apparatus according to the present invention is the information reproducing apparatus which reproduces the data from the recording medium by utilizing the partial response system and decodes the data by using the shift register on the basis of the Viterbi decoding method, wherein the shift register includes the flip-flops Daj as the plurality of latch means connected in series for latching the data and the XOR gates 31a to 31d as the arithmetic means which are disposed between the adjacent flip-flops Daj to carry out CRC calculation and which calculates the exclusive-ORs of the outputs of the flip-flops Daj.
