Recorded magnetization analysis by computer simulation

A new method is proposed for accurately differentiating between an effective recorded-track area and an erase band by making a correlative evaluation of the magnetic-pole density distribution.

Description
Summary:A new method is proposed for accurately differentiating between an effective recorded-track area and an erase band by making a correlative evaluation of the magnetic-pole density distribution. At each end of an effective track, there is an area where a magnetization transition phase-shift occurs. This phase-shift area causes interference between consecutive bits at high-density recording, and reduce the effective track width. Also, an erase band is formed just outside the effective track. Simulation showed that the phase-shift area and the erase band are affected by the recording field distribution and narrowing the gap length, and reducing the recording magnetic field can effectively reduce these areas.
