Book excerpt: Magnetic recording has been the technology of choice of massive storage of information. The hard-disk drive industry has recently undergone a major technological transition from longitudinal magnetic recording (LMR) to perpendicular magnetic recording (PMR). However, convention perpendicular recording can only support a few new product generations before facing insurmountable physical limits. In order to support sustained recording areal density growth, new technological paradigms, such as energy-assisted recording and bit-patterined media recording are being contemplated and planned. In this talk, we will briefly discuss the LMR-to-PMR transition, the extendibility of current PMR recording, and the nature and merits of new enabling technologies. We will also discuss a technology roadmap toward recording densities approaching 10 Tv/in2, approximately 40 times higher than in current disk drives.

Book Synopsis Roadmap for 10 $Gb/in[superscript]2$ Media: Challenges by : Edward S. Murdock
Download or read book Roadmap for 10 $Gb/in[superscript]2$ Media: Challenges written by Edward S. Murdock and published by . This book was released on 1992 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "The history of rigid disk magnetic recording shows a sustained growth in areal density by a factor of ten per decade for forty years. Recent technology demonstrations by IBM and Hitachi promise a continuation of that growth rate for the next ten years. This paper applies informed speculation to the question of what advances in media technology will be necessary to continue the trend to 10 Gb/in2. We apply a read/write model to examining the media properties required for this density in a practical drive application. We also consider the trends in media microstructure and noise, some physical limitations of present materials and a brief look at candidate materials systems for 10 Gb/in2 recording. Some revolutionary changes in media technology appear to be necessary to support this recording density."

Book Synopsis Perpendicular Magnetic Recording by : Sakhrat Khizroev
Download or read book Perpendicular Magnetic Recording written by Sakhrat Khizroev and published by Springer Science & Business Media. This book was released on 2004-08-11 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic recording is expected to become core technology in a multi-billion dollar industry in the in the very near future. Some of the most critical discoveries regarding perpendicular write and playback heads and perpendicular media were made only during the last several years as a result of extensive and intensive research in both academia and industry in their fierce race to extend the superparamagnetic limit in the magnetic recording media. These discoveries appear to be critical for implementing perpendicular magnetic recording into an actual disk drive. This book addresses all the open questions and issues which need to be resolved before perpendicular recording can finally be implemented successfully, and is the first monograph in many years to address this subject. This book is intended for graduate students, young engineers and even senior and more experienced researchers in this field who need to acquire adequate knowledge of the physics of perpendicular magnetic recording in order to further develop the field of perpendicular recording.

Download or read book Comprehensive Nanoscience and Technology written by and published by Academic Press. This book was released on 2010-10-29 with total page 2785 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Introduction: Nanotechnology and its underpinning sciences are progressing with unprecedented rapidity. With technical advances in a variety of nanoscale fabrication and manipulation technologies, the whole topical area is maturing into a vibrant field that is generating new scientific research and a burgeoning range of commercial applications, with an annual market already at the trillion dollar threshold. The means of fabricating and controlling matter on the nanoscale afford striking and unprecedented opportunities to exploit a variety of exotic phenomena such as quantum, nanophotonic and nanoelectromechanical effects. Moreover, researchers are elucidating new perspectives on the electronic and optical properties of matter because of the way that nanoscale materials bridge the disparate theories describing molecules and bulk matter. Surface phenomena also gain a greatly increased significance; even the well-known link between chemical reactivity and surface-to-volume ratio becomes a major determinant of physical properties, when it operates over nanoscale dimensions. Against this background, this comprehensive work is designed to address the need for a dynamic, authoritative and readily accessible source of information, capturing the full breadth of the subject. Its six volumes, covering a broad spectrum of disciplines including material sciences, chemistry, physics and life sciences, have been written and edited by an outstanding team of international experts. Addressing an extensive, cross-disciplinary audience, each chapter aims to cover key developments in a scholarly, readable and critical style, providing an indispensible first point of entry to the literature for scientists and technologists from interdisciplinary fields. The work focuses on the major classes of nanomaterials in terms of their synthesis, structure and applications, reviewing nanomaterials and their respective technologies in well-structured and comprehensive articles with extensive cross-references. It has been a constant surprise and delight to have found, amongst the rapidly escalating number who work in nanoscience and technology, so many highly esteemed authors willing to contribute. Sharing our anticipation of a major addition to the literature, they have also captured the excitement of the field itself in each carefully crafted chapter. Along with our painstaking and meticulous volume editors, full credit for the success of this enterprise must go to these individuals, together with our thanks for (largely) adhering to the given deadlines. Lastly, we record our sincere thanks and appreciation for the skills and professionalism of the numerous Elsevier staff who have been involved in this project, notably Fiona Geraghty, Megan Palmer and Greg Harris, and especially Donna De Weerd-Wilson who has steered it through from its inception. We have greatly enjoyed working with them all, as we have with each other.

Book Synopsis Media Fabrication and Characterization Systems for Three Dimensional-multilevel Magnetic Recording by : Nissim Amos
Download or read book Media Fabrication and Characterization Systems for Three Dimensional-multilevel Magnetic Recording written by Nissim Amos and published by . This book was released on 2008 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The data storage industry recently substituted its five-decade-old technology (longitudinal magnetic recording), which reached its fundamental limitations due to thermal instabilities in the recording media, with perpendicular magnetic recording. Nonetheless, the lifetime of this newly adopted technology and other next generation alternatives including heat-assisted magnetic recording (HAMR) and bit patterned media (BPM) is comparably short. In order to defer the superparamagnetic limit substantially beyond 1 Tbits/in 2, it may be necessary to stack information in a third (vertical) dimension.

Download or read book Tribology and Mechanics of Magnetic Storage Devices written by Bharat Bhushan and published by Springer. This book was released on 2012-02-22 with total page 1019 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic recording is presently a $50 billion industry. It spans audio, video, and digi tal applications in the form of tapes and disks. The industry is expected to grow by a factor of five or more in the next decade. This growth will be accompanied by dramatic improvements in the technology, and the potential exists for magnetic-recording den sities to improve by at least one order of magnitude! Magnetic-recording process is accomplished by relative motion between a mag netic head and a magnetic medium. Types of magnetic media for digital recording are: flexible media (tapes and floppy disks) and rigid disks. Physical contact between head and medium occurs during starts and stops and hydrodynamic air film develops at high speeds. Hying heights (mean separation between head and medium) are on the order of 0. 1 micrometer comparable to surface roughness of the mating members. Need for higher and higher recording densities requires that surfaces be as smooth as possible and flying heights be as low as possible. Smoother surfaces lead to increased static/ kinetic friction and wear. In the case of magnetic tapes, in order to have high bit capac ity for a given size of a spool, we like to use as thin a tape substrate as possible. Thinner tapes are prone to local or bulk viscoelastic deformation during storage. This may lead to variations in head-tape separations resulting in problems in data reliability.
Book Synopsis Storage Systems by : Alexander Thomasian
Download or read book Storage Systems written by Alexander Thomasian and published by Academic Press. This book was released on 2021-10-13 with total page 748 pages. Available in PDF, EPUB and Kindle. Book excerpt: Storage Systems: Organization, Performance, Coding, Reliability and Their Data Processing was motivated by the 1988 Redundant Array of Inexpensive/Independent Disks proposal to replace large form factor mainframe disks with an array of commodity disks. Disk loads are balanced by striping data into strips—with one strip per disk— and storage reliability is enhanced via replication or erasure coding, which at best dedicates k strips per stripe to tolerate k disk failures. Flash memories have resulted in a paradigm shift with Solid State Drives (SSDs) replacing Hard Disk Drives (HDDs) for high performance applications. RAID and Flash have resulted in the emergence of new storage companies, namely EMC, NetApp, SanDisk, and Purestorage, and a multibillion-dollar storage market. Key new conferences and publications are reviewed in this book.The goal of the book is to expose students, researchers, and IT professionals to the more important developments in storage systems, while covering the evolution of storage technologies, traditional and novel databases, and novel sources of data. We describe several prototypes: FAWN at CMU, RAMCloud at Stanford, and Lightstore at MIT; Oracle's Exadata, AWS' Aurora, Alibaba's PolarDB, Fungible Data Center; and author's paper designs for cloud storage, namely heterogeneous disk arrays and hierarchical RAID. Surveys storage technologies and lists sources of data: measurements, text, audio, images, and video Familiarizes with paradigms to improve performance: caching, prefetching, log-structured file systems, and merge-trees (LSMs) Describes RAID organizations and analyzes their performance and reliability Conserves storage via data compression, deduplication, compaction, and secures data via encryption Specifies implications of storage technologies on performance and power consumption Exemplifies database parallelism for big data, analytics, deep learning via multicore CPUs, GPUs, FPGAs, and ASICs, e.g., Google's Tensor Processing Units
