A systematic investigation of the switching behavior and writeability characteristics of perpendicular magnetic oxide media was performed by varying the number of oxide layers as well as the anisotropy Ku gradient in multilayered oxides. The media sw

The effect of interlayer thickness (tIL) on recording performance of the media showing relatively close to coherent switching behavior is investigated. The range of t IL was widely controlled from 20 to 45 nm by inserting an amorphous CrTa filling la

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

Thermal stability is critical for magnetic grains in high density recording applications. Composite media grains consisting primarily of a hard and soft layer with intergrain exchange coupling are examined. Here it is shown, as in single domain parti

We describe a method for the experimental characterization of intrinsic switching field distributions in perpendicular media. The method is based upon a comparison between the major loop and a set of recoil loops, which start at a certain distance /s

This paper investigates the effect of varying the exchange-break-layer thicknesses (leading to a change in intergranular exchange) on spectral rolloff and the transition parameter (a-parameter). The rolloff curves are obtained by measuring the amplit

In the present paper we investigate the effects of adjacent track interference (ATI), which include changes in amplitude, erase band width, and byte error rate. In-depth understanding of these effects, called adjacent track interference (ATI), is of

A magnetometry method was developed for the experimental characterization of intrinsic switching field distributions in perpendicular media. The applied field difference /spl Delta/H between the various recoil loops and the major loop was measured fo
