Abstract

The read/write head shown in the IBM Technical Disclosure Bulletin at Volume 15, No. 4, September 1972, pages 1206-1207, can be modified to increase its output. By placing the magnetoresistive (MR) element into physical and magnetic contact with one of the ferrite members, the output signal of the head is greatly increased during reading. This is true whether or not the write conductor is included in the structure.

Magnetic Transducer

The read/write head shown in the IBM Technical Disclosure Bulletin at Volume 15, No. 4, September 1972, pages 1206-1207, can be modified to increase its output. By placing the magnetoresistive (MR) element into physical and magnetic contact with one of the ferrite members, the output signal of the head is greatly increased during reading. This is true whether or not the write conductor is included in the structure.

In one modification, a second MR element may be included in the head, spaced in parallel to the first MR element, with the magnetic field generated by each of the MR elements magnetically biasing the other MR element. In such a modified structure, each MR element may be placed into physical contact with the ferrite shield nearest to it to increase the signal output during reading.
