The performance of dual-stripe magnetoresistive heads in near contact
The suitability of a dual-stripe magnetoresistive (DSMR) head for near-contact recording is investigated. Common mode rejection of thermally induced pulses is derived by a model incorporating manufacturing tolerance, and verified experimentally. The rejection ratio is at least 20 dB. Experiments also indicated that a DSMR can survive near-contact conditions without premature degradation.
