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