Abstract
This paper simulates the adjacent track erasure vs. amount of track squeeze of a perpendicular recording media with high coercivity, as a function of skew angle using micromagnetic modelling. LLG equation and finite element of the magnetic head field is used in the analysis. The fact that erase width is narrower than write width can be attributed to the insufficient reverse overwrite as is evident in the presence of a small amount of on track signal left after erasure.
