A hybrid read/write/erase head has its read element produced by batch fabricating thin film elements of magnetoresistive material, for instance, onto a block of ferrite material. The individual elements are diced and lapped and bonded to an inductive ferrite pole piece as part of the pole structure. The back edge of the read element forms a part of the gap of the write/erase section of the head. As shown in the figure, the head includes an inductive pole piece 10 which has a conductor coil 11 wrapped around a portion of its length. A chip portion 12 of ferrite forms part of the write/erase gap 13 and includes a read transducer element 14 deposited on the outside edge. A closure block 15 of ferrite completes the magnetic path for the head.
