Abstract
The reproduce performance of a narrow-track (2 micron) dual magnetores istive (DMR) reproduce head is theoretically analyzed using three-dime nsional micromagnetic modelling. Down-track and cross-track response, side-reading, and nonlinear effects are considered. The DMR blas state with antiparallel components of blas magnetization is shown to maximi ze performance. Single-domain stabilization of the antiparallel DMR, c omparison to the shielded-MR, and the shielded-DMR are discussed.
