Abstract
A planar silicon magnetoresistive read/write head has separate read and write gaps that can be individually optimized. The write gap includes a write gap shunt that suppresses signals that are read across the write gap without interfering with the ability of the head to generate write signals at the write gap. The head retains both the advantages of removing the magnetoresistive element from the air bearing surface to avoid wear, shorting, and corrosion, and to eliminate cross-track asymmetry, associated with dual gap magnetoresistive heads; and the advantages of low cost fabrication and high area density, associated with silicon planar head structures.
