Making a Data CD

A data CD (also known as a CD-ROM), is a compact disc used to

store computer data. Data is written on the CD in a continuous spi-

ral running from the center of the CD to its outside rim. All the bits

in a file are written one after the other from beginning to end, then

the next file is written, and so on.

A logical format (or file system) structures the raw bits on the CD in

a virtual

tree

of directories and files, which makes it easier for both

humans and computers to use the information. ISO 9660 is a world-

wide standard specifying the logical format for files and directories

on a CD-ROM.

Typical uses for CD-ROMs include:

■

Archiving data

■

Backing up a hard drive or other media

■

Creating a test copy of a CD before having it factory-

duplicated

■

Disseminating information to field offices
