The use of bit-patterned media is one of the approaches being investigated to extend
magnetic recording densities to 1 Tbit/in 2 and beyond. In patterned media, track pitch may …

In bit-patterned magnetic recording (BPMR), inter-track interference (ITI) becomes a major
impairment due to the small track pitch. One way to mitigate the ITI is to equalize the read …

The size, shape, and distribution of islands in a patterned medium depends on the
patterning process adopted. The off-track performance in this case is mainly dominated by …

The application of a deep neural network (DNN) as the detection channel for hard disk drive
(HDD) data recovery at high user bit density and the prominent magnetic transition jitter …

Two-dimensional magnetic recording (2-D TDMR) is an emerging technology that aims to
achieve areal densities as high as 10 Tb/in 2 using sophisticated 2-D signal-processing …

We introduce an iterative two-dimensional (2-D) soft output Viterbi algorithm (SOVA) for
patterned media storage. Patterned media storage has enormous 2-D intersymbol …

Conventional magnetic recording technologies are expected to reach storage density limits
in the near future. Therefore, using new technologies is essential to obtain high densities …

Many view data storage on patterned magnetic media as one way of attaining storage
densities in excess of 1 Tb/in/sup 2/and thus overcoming the problems associated with …

Shingled magnetic recording is a promising option to sustain the historical areal density
growth of hard disk drives while retaining conventional heads and media. Nevertheless …

In this article, we demonstrate a convolutional neural network (CNN)-based data detection
channel on real data from a commercial hard disk drive (HDD) employed with two …
