This paper proposes a new approach to magnetic recording based on shingled writing and two-dimensional readback and signal-processing. This approach continues the use of conventional granular media but proposes techniques such that a substantial frac

A perpendicular recording system that allows areal densities beyond 200 Gbit/in 2 has been designed and tested to investigate the major challenges in perpendicular magnetic recording. The integrated write/read head has a trailing shield to improve th

To explore recording head challenges for perpendicular recording at 200 Gb/in/sup 2/ and beyond, the design, fabrication and performance of narrow track dual-element heads were studied using an ABS trailing shield writer design and a conventional CIP

Transition noise and jitter of perpendicular media are improved by writing with pole heads which have trailing shields. This phenomenon may be studied by using forward and backward flying longitudinal ring heads. The forward-flying ring heads write f

This paper analyzes the write field profiles for perpendicular head designs that have been proposed for reaching 1 Tb/in/sup 2/. Designs considered include side shielded poles and high anisotropy poles. A vector Stoner-Wohlfarth writing criteria is u

A cross-track noise profile measurement is developed for identifying the source of adjacent-track interference (ATI) fields in perpendicular recording systems. The noise amplitude as a function of cross-track position and write current clearly deline

The effect of a magnetic trailing shield located in close proximity of the pole tip for a perpendicular write head has been studied in a perpendicular recording system. For a 150nm wide write pole, the write field gradient is improved yielding a 40%
