Abstract
Evaluation of the distortion resulting from imperfect biasing of a magnetoresistive (MR) read head shows that it is unacceptable in wide band recording systems. A general solution to the problem is presented which involves differentially sensed elements. A practical implementation and performance of a shielded head is discussed. Analytical techniques are shown for designing current-biased MR heads, which allow predictions of performance closely matching experimental results.
