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

High-resolution magnetic force microscopy (hrMFM) has been used to investigate the write characteristics of forward and reverse flying heads on perpendicular recording media with soft underlayers. hrMFM has the advantage that it provides much better

The track width performance of giant magnetoresistive (GMR) read heads defined by e-beam lithography was studied in a series of recording tests. Results on longitudinal media showed slow reductions of magnetic versus physical read widths below 100 nm

Adjacent-track interference (ATI) in a dual-layer perpendicular recording system arises during both writing and reading. During writing, the stray fields from the write head can cause side writing and side erasure. A dc-erase method using media with

The thermal stability of coupled granular/continuous (CGC) perpendicular media is supported by fundamental modeling and experimental results, including spin-stand testing. By incorporating the interlayer exchange coupling into the model, the simulati

A potential advantage of perpendicular recording derives from the supposition that the perpendicular geometry, with the medium effectively in the write gap, permits higher anisotropy media for a given head saturation induction. We test these conjectu

This paper reviews the material properties of Fe-AlN high moment soft magnetic material, and discusses the design, fabrication and performance of write heads using this material. These write heads comprise two designs. The first had FeAlN for both to

As magnetic recording areal density increases the mechanical spacing between the head and the disk continues to shrink. Head protrusion, induced by write current heating of the coil and yoke during recording at operating temperature, may interfere wi
