Book Description
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.

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
