Abstract:
The magnetic medium includes a soft magnetic layer separated from the hard magnetic recording layer by a nonmagnetic buffer layer. Virtual magnetic images induced in the soft magnetic layer reduce off-track magnetization seen by the recording head. Thus, interference caused by tracks adjacent to the track being read is reduced.
