Research on Error Diffusion in Bit Patterned Media

摘要

The presence on any variation in the magnetization direction of an island has a detrimental effect on the ability to recover recorded data. To approve this, Ansys Finite Element Method software has been used to simulate the magnetic field intensity distribution in bit patterned media, from the result. It is seen the magnetization direction variations because of thermal fluctuation can cause errors, But this errors can not diffusion, It is isolated.
