摘要： The application discloses pole tip shield assemblies for a magnetic write element. The shield assemblies disclosed include side shields to limit adjacent track interference. The side shields are truncated or notched at a midpoint to form an expanded non-magnetic gap along a trailing portion of the pole tip to enhance write field and/or field gradient. The expanded non-magnetic gap region is larger than the non-magnetic gap region along a leading portion of the pole tip.

摘要： A magnetic storage device comprises a magnetic recording medium; a writing/reading element for storing information on the magnetic recording medium by generating a write field in order to switch regions within the magnetic recording medium in accordance with the information to be stored and reading stored information from the magnetic recording medium by sensing the switched regions within the recording medium and a layer-addressing means for addressing different layers of the magnetic recording medium by applying an oscillating magnetic layer address field in addition to the write field and by controlling the frequency of the oscillating magnetic field so that regions in different layers of the magnetic recording medium can be selectively switched and read.
