A fully updated version of the popular Introduction to Tribology, the second edition of this leading tribology text introduces the major developments in the understanding and interpretation of friction, wear and lubrication.&nbsp; Considerations of friction and wear have been fully revised to include recent analysis and data work, and friction mechanisms have been reappraised in light of current developments. &nbsp; In this edition, the breakthroughs in tribology at the nano- and micro- level as well as recent developments in nanotechnology and magnetic storage technologies are introduced. A new chapter on the emerging field of green tribology and biomimetics is included.&nbsp; <ul> <li>Introduces the topic of tribology from a mechanical engineering, mechanics and materials science points of view</li> <li>Newly updated chapter covers both the underlying theory and the current applications of tribology to industry</li> <li>Updated write-up on nanotribology and nanotechnology&nbsp; and introduction of a new chapter on green tribology and biomimetics</li> </ul> &nbsp;

Mechanics and Reliability of Flexible Magnetic Media

Springer New York

According to some estimates, 95% of information today is stored on paper, 3% on microfiche, and only 2% on magnetic/optical and semiconductor storage devices. Semiconductor storage is almost exclusively used for dy­ namic random access memory (D-RAM) in computers, and constitutes a very small fraction of the total storage capacity. Magnetic storage devices include hard disk, flexible disk, and tape drives. Estimates for worldwide storage is 12,000 petabytes (12 million terabytes). It is estimated that mag­ netic tapes store about 95% of the information, and the balance is stored equally by magnetic hard disk and optical disk drives (250 petabytes each). 14 For comparisons, the human brain has 10 neurons and holds approxi­ mately 200 megabytes of information. For a world population of 6 billion people, the total human memory is therefore 1200 petabytes, which is about 10% of the electronically recorded information. Magnetic and optical storage industry for consumer and data recording applications is at present an industry grossing more than $80 billion per year. It is expected to grow at cumulative rate of about 10% per year. Revenue is as follows: for magnetic disks and drives, about $35 billion; for flexible disks and drives, about $4 billion ($1.5b/$2.5b); for data tape and tape drives, about $8 billion ($2b/$6b); for consumer video- and audiotape and tape drives, about $25 billion ($8b/$17b); for CD/DVD read-only disk and disk drives, about $7 billion ($lb/$6b); and for other optical products, less than a $1 billion.

The first of its kind, this book is a systematic compilation of current knowledge of mechanics and reliability of flexible magnetic media. Chapter 1 presents the brief descriptions of physics of magnetic recording, magnetic storage systems and manufacturing processes of magnetic media. Chapter 2 presents a brief description of manufacturing processes of poly (ethylene terephthalate) films commonly used as flexible media substrate, and physical and chemical properties of the PET films and coated magnetic media. Chapter 4 presents analytical predictions of stresses in wound magnetic tapes and flexible disks. In Chapter 5, long-term reliability problems of magnetic tapes encountered during storage and use are discussed; their descriptions, mechanisms and methods of preventing them are presented. In Chapter 6, long-term reliability problems of flexible disks encountered during storage and use are discussed. Viscoelasticity theories presented in this book are very general and are applicable in systems other than magnetic-storage ones. This book is intended for three types of readers: graduate students of magnetic recording, the research worker who intends to become active in this field, and the practicing engineer who has encountered a reliability problem and hopes to solve it as expeditiously as possible.
