PROBLEM TO BE SOLVED: To provide a magnetic medium reader having efficiency higher than a magnetic medium read channel by conventional technique. SOLUTION: An artificial neuro network 220 processing a signal from a magnetic read head is applied to a magnetic read channel 200. An electronic signal from the magnetic read head amplified by a preamplifier is stored in a delay line as the delayed continuous indicated value of the amplified electronic signal. The artificial neuro network 220 receives the delayed continuous indicated value from the delay line, and reconstructs a data signal received from the magnetic read head, and a reconstructed data signal and a reconstructed synchronous signal are generated. The artificial neuro network 220 is prepared preferably as a forward output type 7-3-2 perfect coupling network. The above- mentioned reconstructing process is executed through a training process beforehand carried out for determining an optimum nerve-cell weighting set value for reconstruction by utilizing a training set consisting of known data and clocks.
