Magnetoresistive read/write head with high-performance gap layers

Image Number 2 for United States Patent #6188549.

High-performance amagnetic gap layers for electromagnetic transducers are thermally conductive and electrically insulative, as well as providing a dense amorphous surface for forming magnet resistive sensor elements. The amagnetic gap layers include nonmonocrystalline compounds of AIN, SiC, SiO.sub.2, Si.sub.3 N.sub.4, BeO and Ta.sub.2 O.sub.3. The layers provide greatly increased thermal conductivity and breakdown voltage as compared with alumina, and are particularly suited for giant magnetoresistive and spin-valve heads.
