Magnetic recording at the highest areal density on conventional granular recording media uses $\sim 10$ grains to carry each bit of customer data. Efforts to reduce this number have focused on improving the resolution of the writing and reading proce

Bit-patterned (BP) recording is a candidate for extending magnetic data storage towards 10 Tb/in 2 bit densities. An analysis of the design tolerances is carried out using dynamic micromagnetic simulations and statistical models. The effects of distr

A fully-automated pole-tip shape optimization tool, involving write head geometry construction, meshing, micromagnetic simulation and evaluation, is presented. Optimizations have been performed for three different writing schemes (centered, staggered

Bit Patterned Media (BPM) for magnetic recording provide a route to densities $>1 Tb/in^2$ and circumvents many of the challenges associated with conventional granular media technology. Instead of recording a bit on an ensemble of random grains, BPM

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

Magnetic recording at fast data rates requires write heads with rapid rise times of the magnetic flux during the write process. We present three-dimensional (3D) micromagnetic finite element calculations of an entire ring head including 3D coil geome

Recent advances in magnetic recording technology are increasing the relevance of simulation to magnetic media design. In particular, the difficulties inherent in developing perpendicular recording technology require the write process to be modeled at

We describe micromagnetic simulations to examine the effect of intergranular exchange on thermal stability of dibit transitions in perpendicular media. We found that, without an intergranular exchange, pure magnetostatic interactions induce substanti
