Abstract
An improved magnetic tape transducer of the type having both a write head and a read head in the same assembly, includes asymmetrical shields disposed on either side of a magnetoresistive element comprising the read head in order to reduce magnetic feedthrough between the write head and the read head. The shield upon the side of the magnetoresistive element which is closer to the write head has a thinner cross-section than the shield on the other side, thereby balancing the amount of coupled flux from the write head and reducing the resultant feedthrough.
