While there have been remarkable advances in recent years in the
areas of both coding and detection for data storage, this book
focuses on data detection, or the processing of reading back
waveforms to reproduce stored data, in conjunction with the
traditional modulation coding method called run-length-limited or
(d, k) coding. Among notable recent advances in the area of data
detection is the application of the Viterbi algorithm combined with
partial response linear equalization, known as partial response
maximum likelihood (PRML), to commercial magnetic disk drives. The
decision feedback equalizer (DFE), a well established data
detection technique in communication channels subject to
intersymbol interference (ISI), has also attracted attention in the
magnetic recording community. One of the objectives of this book is
to provide a tutorial review of the application of these detection
schemes to magnetic recording. Philosophies behind these detection
schemes are explained, as well as methods for analyzing their
performances.Performance of these detection schemes is compared
with that of the traditional peak detection method to provide
insight into density improvements that can be achieved using these
schemes. The main emphasis of the book is on the more recent idea
proposed by the authors, namely, the application of fixed delay
tree search (FDTS) to high density magnetic recording. Although the
idea of depth-limited tree search has long existed in coding and in
detection for ISI channels, it has not been previously noted that,
for certain constrained ISI channels, depth-limited tree search
yields an asymptotically optimal performance. This book explores
the idea of depth-limited search on constrained channels and shows
how a relatively simple FDTS detector combined with DFE, called
FDTS/DF, achieves a near-optimal performance when applied to high
density magnetic recording where the minimum run-length constraint
may be required to suppress nonlinearities and media noise.
