摘要： A magnetic reproducing apparatus plays back a magnetic recording medium (2) on which digital data have been magnetically recorded through a partial response encoder (1). The magnetic reproducing apparatus includes a synchronizing signal data detector (3) for detecting a synchronizing signal data part from a reproduced signal data series, a transmission path characteristics estimator (4) for modeling an impulse response between a recording system (7) and a reproducing system (8) with the synchronizing signal data part detected by the synchronizing signal data detector (3) being used as a reference signal, and a decoder (5) for decoding a recorded signal data series according to a Viterbi algorithm based on a transmission model produced by the transmission path characteristics estimator (4).
