With 26 entirely new and 5 extensively revised chapters out of the total of 39, the Mobile
Communications Handbook, Third Edition presents an in-depth and up-to-date overview of …

Rapid advances in recording materials, read/write heads, and mechanical designs over the
last 15 years have led to the need for more complicated signal processing, coding, and …

Maximum and near-maximum likelihood sequence detectors in signal-dependent noise are
discussed. It is shown that the linear prediction viewpoint allows a very simple derivation of …

A heat assisted magnetic recording composite media with a superparamagnetic writing layer
is proposed. The recording process is initiated in the write layer that is magnetically softer …

Heat-assisted magnetic recording (HAMR) is a promising approach to increase the areal
density of hard disk drives. The purpose of this paper is to provide a computational …

A novel system design for sensing very high density magnetic recording data, such as that
envisioned for two-dimensional magnetic recording, is proposed. The key idea is a rotated …

Two techniques which improve the performance of partial response maximum likelihood
systems (PRML) without increasing the number of states in the Viterbi algorithm (VA) are …

The present invention relates to a system for combating pattern-dependent media noise in a
signal. More particularly, the present invention relates to a system for reducing the total …

As the areal recording density increases at a 60% annual rate, it becomes a challenge to
design a head that achieves media noise limited recording performance. Since the noise of …

High density data storage systems suffer from the presence of data dependent noise during
the read-back process. Detection methods such as the standard Viterbi algorithm (VA) are …
