Constrained codes are a key component in digital recording devices that have become
ubiquitous in computer data storage and electronic entertainment applications. This paper …

As one of the most classical data-storage systems, magnetic recording (MR) systems have
attracted a significant amount of research attention in the past several decades due to the …

This paper explores the feasibility of implementing conventional magnetic recording
technology at densities up to one Terabit per square inch. The key limiting physical factor is …

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 …

A simplified general expression is given for SNR for digital magnetic recording for transition
noise dominant systems. High density media are assumed in which the transition parameter …

The partial response channel can be viewed as a rate-1 encoder in which the output
alphabet differs from the input alphabet. In serially concatenated coding schemes, the partial …

The recent proposal of tilted perpendicular recording for Tb/in 2 densities is extended here
to examine the effects of intergranular exchange and anisotropy distributions on signal-to …

In this paper, we present a review of the write and read processes in perpendicular magnetic
recording. We also discuss their impact, based on recording physics aspects, on design …

This paper proposes a new signal-to-noise ratio (SNR) definition for magnetic recording
channels with both additive and medium noise components. The proposed SNR is a …

A thermal Williams-Comstock recording model was developed to predict the transition length
in a longitudinal heat-assisted magnetic recording system. In this paper, we compare the …
