Abstract
Advances in 3D simulations of magnetoresistive heads and media are com bined to permit detailed analysis of track-edge recording effects in h ard disk applications. Vector Preisach models for thin film media were combined together with 3D micromagnetic models of dual stripe heads i nto a single simulation system. This has permitted prediction of servo gain non-linearities in dual stripe heads used in embedded servo disk drives. The models are used to determine the impact of linewidth and alignment tolerances on servo gain nonlinearity.
