An inductive write head has its write poles and write gap oriented to
generate magnetic fields in the cross-track direction on a magnetic
recording disk in a disk drive. The disk has the magnetizations in the
concentric data tracks oriented in the cross-track direction with the
concentric data tracks magnetically separated from each other by guard
bands. The write head may have an erase pole and an erase gap to generate
magnetic fields in an along-the-track direction on the sides of the data
tracks, with the along-the-track magnetizations serving as the guard
bands.
