The CD-ROM and Optical Disc Recording Systems


Book Description

With one million CD-ROM users worldwide, there is an urgent need to demystify the technology of compact-disc data recording and retrieval, which will eventually replace the floppy disk. This book meets that need. It will benefit students, engineers, and professionals from many disciplines whowish to understand and exploit the cost-effective potential of optical data storage and retrieval. The book provides a unique introduction to CD-ROM and other optical recording systems, and clearly describes how the two main competing systems--the magneto-optic and the phase change types--work.Topics include photodetectors, lasers, mastering, WORM media, and magneto-optic media, among others. Keep up to date with this superb new introduction to CD-ROM and optical disc recording systems.




Origins and Successors of the Compact Disc


Book Description

In March 1979, a prototype of a ‘Compact Disc (CD) digital audio system’ was publicly presented and demonstrated to an audience of about 300 journalists at Philips in Eindhoven, The Netherlands. This milestone effectively marked the beginning of the digital entertainment era. In the years to follow, the CD-audio system became an astonishing worldwide success, and was followed by successful derivatives such as CD-ROM, CD-RW, DVD, and recently Blu-ray Disc. Today, around the thirtieth anniversary of the milestone, it is taken for granted that media content is stored and distributed digitally, and the analog era seems long gone. This book retraces the origins of the CD system and the subsequent evolution of digital optical storage, with a focus on the contributions of Philips to this field. The book contains perspectives on the history and evolution of optical storage, along with reproductions of key technical contributions of Philips to the field.







CD and DVD Forensics


Book Description

CD and DVD Forensics will take the reader through all facets of handling, examining, and processing CD and DVD evidence for computer forensics. At a time where data forensics is becoming a major part of law enforcement and prosecution in the public sector, and corporate and system security in the private sector, the interest in this subject has just begun to blossom.CD and DVD Forensics is a how to book that will give the reader tools to be able to open CDs and DVDs in an effort to identify evidence of a crime. These tools can be applied in both the public and private sectors. Armed with this information, law enforcement, corporate security, and private investigators will be able to be more effective in their evidence related tasks. To accomplish this the book is divided into four basic parts: (a) CD and DVD physics dealing with the history, construction and technology of CD and DVD media, (b) file systems present on CDs and DVDs and how these are different from that which is found on hard disks, floppy disks and other media, (c) considerations for handling CD and DVD evidence to both recover the maximum amount of information present on a disc and to do so without destroying or altering the disc in any way, and (d) using the InfinaDyne product CD/DVD Inspector to examine discs in detail and collect evidence. - This is the first book addressing using the CD/DVD Inspector product in a hands-on manner with a complete step-by-step guide for examining evidence discs - See how to open CD's and DVD'd and extract all the crucial evidence they may contain




Digital Audio and Compact Disc Technology


Book Description

Digital Audio and Compact Disc Technology, Second Edition presents the principles behind the development of the compact disc digital audio system. The book discusses the aspects of digital audio and compact disc technology, which has revolutionized the way music is recorded and consumed. The text contains chapters that discuss the principles of digital signal processing, such as, sampling, quantization and error correction; codes for digital magnetic recording; an overview of the compact disc medium; compact disc encoding; and digital audio recording systems. Electronics enthusiasts and engineers will find the book informative.

Accompanying DVD-ROM (i.e.: hybrid DVD-Video/DVD-ROM) contains ... "dynamic application of DVD technology with samples from Dolby, DTS, THX, IMAX, Joe Kane Productions, Microsoft, Widescreen Review, and others, plus audio/video tests, WebDVD, HTML files, spreadsheets, and more."--Page 4 of cover.




The CD-ROM Drive


Book Description

The Compact Disc (CD), as a standardized information carrier, has become one of the most successful consumer products ever marketed. Although the original disc was intended for audio playback, its specific advantages opened very quickly the way towards various computer applications. The standardization of the Compact Disc Read-Only Memory (CD-ROM) and of all succeeding similar products, like Compact Disc interactive (CD-i), Photo and Video CD, CD Recordable (CD-R), and CD Rewritable (CD R/W), has substantially enlarged the range of possible applications. The plastic disc represented from the very beginning a removable medium of large storage capacity. The advent of the personal computer accompa nied by the increasing demand for both data distribution and exchange have strongly marked the evolution of the CD-ROM drive. The number of sold CD-ROM units exceeded 60 millions in 1997 when compared to about 2.5 millions in 1992. As computing power continuously improved over the years, computer pe ripherals have also targeted better performance specifications. In particular, the speed of CD-ROM drives increased from the so-called 1X in 1984 to dou ble speed in 1992, and further to 32X at the beginning of 1998. The average time needed to access data on disc has dropped from about 300 ms to less than 90 ms within the same period of time.




Multimedia Systems


Book Description

Multimedia Systems discusses the basic characteristics of multimedia operating systems, networking and communication, and multimedia middleware systems. The overall goal of the book is to provide a broad understanding of multimedia systems and applications in an integrated manner: a multimedia application and its user interface must be developed in an integrated fashion with underlying multimedia middleware, operating systems, networks, security, and multimedia devices. Fundamental characteristics of multimedia operating and distributed communication systems are presented, especially scheduling algorithms and other OS supporting approaches for multimedia applications with soft-real-time deadlines, multimedia file systems and servers with their decision algorithms for data placement, scheduling and buffer management, multimedia communication, transport, and streaming protocols, services with their error control, congestion control and other Quality of Service aware and adaptive algorithms, synchronization services with their skew control methods, and group communication with their group coordinating algorithms and other distributed services.
