MAGNETORESISTIVT MAGNETHUVUD

摘要

A magnetic read head assembly comprises two magnetostatically coupled magnetoresistive (MR) elements, and conducting means for supplying a drive current to the elements. The drive current serves as a sense current as well as a bias current. The drive current is provided to both elements concurrently, so that the current through each element serves to magnetically bias the other element. An output differential read signal is obtained from the two MR elements.
