This book treats the various aspects of noise from magnetic recording media and the impact on system performance. Several authors present discussions of: materials and processes used to fabricate media for computer data storage, theoretical aspects of noise and micromagnetic behavior, experimental methods and characterization, and system analysis. In the past decade thin film recording media have largely displaced particlate media in rigid disk recording systems. During the same period of time the field has evolved from the prevalent belief that thin film media were virtually noiseless to a detailed understanding of the origin and the manifestation of noise in these new media. This understanding has lead to the ability to make the very low noise media needed in present applications. The present state of understanding of both particulate and thin film media is summarized.
An NPR Best Book of 2017 "This is not a book about why vinyl sounds better; it's way more interesting than that . . . it] is full of things I didn't know, like why people yell into cellphones . . . Ultimately, it's about how we consume sound as a society - which is, increasingly, on an individual basis." --NPR "If you're a devoted music fan who's dubious about both rosy nostalgia and futuristic utopianism, Damon Krukowski's The New Analog is for you." --The New York Times Book Review "A pointedly passionate look at what's been lost in the digital era." --Los Angeles Times What John Berger did to ways of seeing, well-known indie musician Damon Krukowski does to ways of listening in this lively guide to the transition from analog to digital culture Having made his name in the late 1980s as a member of the indie band Galaxie 500, Damon Krukowski has watched cultural life lurch from analog to digital. And as an artist who has weathered the transition, he has challenging, urgent questions for both creators and consumers about what we have thrown away in the process: Are our devices leaving us lost in our own headspace even as they pinpoint our location? Does the long reach of digital communication come at the sacrifice of our ability to gauge social distance? Do streaming media discourage us from listening closely? Are we hearing each other fully in this new environment? Rather than simply rejecting the digital disruption of cultural life, Krukowski uses the sound engineer's distinction of signal and noise to reexamine what we have lost as a technological culture, looking carefully at what was valuable in the analog realm so we can hold on to it. Taking a set of experiences from the production and consumption of music that have changed since the analog era--the disorientation of headphones, flattening of the voice, silence of media, loudness of mastering, and manipulation of time--as a basis for a broader exploration of contemporary culture, Krukowski gives us a brilliant meditation and guide to keeping our heads amid the digital flux. Think of it as plugging in without tuning out.
Implementing new architectures and designs for the magnetic recording read channel have been pushed to the limits of modern integrated circuit manufacturing technology. This book reviews advanced coding and signal processing techniques and architectures for magnetic recording systems. Beginning with the basic principles, it examines read/write operations, data organization, head positioning, sensing, timing recovery, data detection, and error correction. It also provides an in-depth treatment of all recording channel subsystems inside a read channel and hard disk drive controller. The final section reviews new trends in coding, particularly emerging codes for recording channels.

Digital Baseband Transmission and Recording provides an integral, in-depth and up-to-date overview of the signal processing techniques that are at the heart of digital baseband transmission and recording systems. The coverage ranges from fundamentals to applications in such areas as digital subscriber loops and magnetic and optical storage. Much of the material presented here has never before appeared in book form. The main features of Digital Baseband Transmission and Recording include: a survey of digital subscriber lines and digital magnetic and optical storage; a review of fundamental transmission and reception limits; an encyclopedic introduction to baseband modulation codes; development of a rich palette of equalization techniques; a coherent treatment of Viterbi detection and many near-optimum detection schemes; an overview of adaptive reception techniques that encompasses adaptive gain and slope control, adaptive detection, and novel forms of zero-forcing adaptation; an in-depth review of timing recovery and PLLs, with an extensive catalog of timing-recovery schemes. . Featuring around 450 figures, 200 examples, 350 problems and exercises, and 750 references, Digital Baseband Transmission and Recording is an essential reference source to engineers and researchers active in telecommunications and digital recording. It will also be useful for advanced courses in digital communications.
