Abstract

A new concept of Dual Magnetoresistive reproductive mode is applied to improve the design and operation of high-performance multi-track Read-While-Write (RWW) heads for tape and/or potential disk applications. RWW operation exists in some magnetic recording units in which verifying what was recorded is necessary. A new multi-track Inductive/Dual Magnetoresistive (DMR) head design is found to reduce the crossfeed noise radiation by about a factor of 20, compared with the conventional Soft-Adjacent-Layer (SAL) Magnetoresistive Heads design, which is the most favoured approach for achieving simultaneous read and write operations, especially in a multi-track head with ultra-narrow trackwidth. To verify these analysis results, measurements with 2.9 /spl mu/m track width inductive/MR and inductive/DMR heads were done.
