Abstract
An amplifier for an MR head comprises a means for switching cut-off frequencies of a plurality of lowpass filters, when a data signal superposed by a disturbance signal (a composite signal) is input from an MR head, a means for extracting the disturbance signal from the composite signal, a means for adding the extracted disturbance signal to the composite signal. Accordingly, it possible to obtain a data signal less influenced and less distorted even if a disturbance signal appears.
