Abstract
Apparatus for reading magnetically stored data from a wide range of magnetic media. The apparatus includes a magnetoresistive MR head for producing a signal representative of stored magnetic data and a hysteresis comparator circuit for processing the signal from high concentration media. The MR head is preferably a paired MR head having a preamplifier circuit which provides the bias current for the PMR head, amplifies the signal produced by the PMR head, and provides rejection of common mode signals.
