Patent abstract
A transducer for magnetically reading and writing information is disclosed. The present invention eases the intricate process of wafer thin film deposition and bar lapping by proposing a transducer including a first and second member, both of which perform the reading and writing function of the transducer. The present invention provides a transducer with greatly improved magnetic efficiency by probing the media magnetization directly. The structure is inherently stable due to shape anisotropy of the members and the closure of magnetic flux at the ends of each member.
