Magnetic Storage Handbook [antikvár]

FOREWORD The Magnetic Storage Handbook is a thoroughly revised and updated version of Part II of the Magnetic Recording Handbook published in 1990. A revised version of Part I has recently been published under the title Magnetic Recording Tectinology. The extent of the revisions and additions made to the various chapters of the Magnetic Storage Handbook have been dictated by how rapidly the subject covered has changed since the earlier handbook was written. Revisions vary from relatively minor (10%) updates to complete rewrites and, in some cases, the recruitment of new authors. The chapters receiving the most extensive revisions are the following: Data Storage on Rigid Disks. This chapter has been extensively updated to reflect the extraordinary achievements made in recent years in producing disk drives combining high capacity, small size, and low cost. Data Storage on Flexible Disks. The major additions here cover the progress made in developing high-capacity, replaceable-disk drives designed to backup hard-disk files. These drives combine sophisticated servo systems and advanced flexible media design, and have capacities two orders of magnitude greater than regular 3.5-inch floppies. Data Storage on Tape. This chapter is entirely new. It covers both fixed and rotating-head tape cartridges, and their primary application in providing large-capacity backup for hard-disk data. Digital Video Recording. Formerly this subject was covered as a part of the chapter on video recording. It now warrants a newly written, greatly expanded, separate chapter. Digital video recording is now firmly established, with digital video tape recorders becoming increasingly available for both professional and consumer applications. Digital Audio Recording. This chapter has been completely rewritten. Other chapters of the Magnetic Storage Handbook required less extensive revision. However, where significant technological advances have occurred in recent years, these are covered by the inclusion of the relevant new data, descriptive text, and appropriate references.
