The book discusses numerous developments in various fields of data storage research, ranging from the design of a hierarchical memory subsystem in embedded signal processing systems for data-intensive applications, through data representation in flash memories, data recording and retrieval in traditional optical data storage systems, and the more recent holographic systems, to applications in medicine requiring large image databases.
You have more data than ever, whether you're an IT expert, manager, or home PC user, and it's more crucial than ever to select dependable, affordable data storage. One of the foremost authorities on data storage in the world discusses all of your options in this book and demonstrates how to maximize them.
The characteristics, benefits, and underlying technology of every modern data storage option are covered in this book, including hard drives, DVDs, CDs, removable media storage systems like Jaz and Zip, tape backup, and RAID.
It presents the pros and cons of every data storage interface, including IDE, SCSI, USB, FireWire, and Fibre Channel. With the multiple overwrite feature, rewritable optical discs have found application in consumer DVD+RW video recorders, professional archiving systems, and computer drives for data storage, replacing the floppy disc in the latter case.
This book also provides an overview of the recording principles, materials aspects, and application areas of phase-change optical storage. Some theoretical background is given to familiarize the reader with the basics of the phase-change processes.
Elements of data recording, including mark formation, erasability, direct overwrite strategies, data quality, data stability, etc are explained and extensively discussed. A mark formation model is described and used throughout the whole book to back-up measurement results and support the discussed applications.
