The potential of bit patterned media in shingled recording

Journal of Magnetism and Magnetic Materials, 2012
Abstract Shingled recording on continuous and bit patterned media (BPM) is compared. From a recording viewpoint, continuous media have the advantage due to the lack of a need to synchronise writing with dot position. For BPM the write windows at 4 Tbit/in 2 are only a couple of nm across, requiring extremely tight manufacturing tolerances.

Repeatable Runout Following in Bit Patterned Media Recording

open access: yes2014 Conference on Information Storage and Processing Systems, 2014
An adaptive feedforward controller design for tracking repeatable runout (RRO) in bit patterned media recording (BMPR) is proposed for single stage hard disk drives (HDD). The technique is based on a modified filtered-x least mean squares (MFX-LMS) algorithm with deterministic periodic input, and a novel variable step size that boosts both the ...

Joint-Track Equalization and Detection for Bit Patterned Media Recording

IEEE Transactions on Magnetics, 2010
We compare several different detection and equalization methods for bit patterned media recording channels. We consider a scheme that utilizes a joint-track equalization technique followed by a Viterbi detector. For certain recording densities, simulation results show that it has essentially the same performance as an optimal detector but with reduced ...

Recording on bit-patterned media at densities of 1Tb/in2 and beyond

INTERMAG 2006 - IEEE International Magnetics Conference, 2006
We present a comprehensive analysis of the areal density potential of a bit-patterned media recording. The recording performance is dominated by written-in errors rather than traditional signal-to-noise considerations. Written-in errors are caused by statistical fluctuations of the magnetic properties and the locations of the individual dots.
