摘要：
A magnetic recording/reproducing apparatus has a magnetoresistive head having a magnetoresistive film through which a current is flowed in a direction substantially perpendicular to a film plane and a pair of magnetic shields disposed to sandwich the magnetoresistive film, and a preamplifier which supplies a sense current to the magnetoresistive head in constant-current driving.
