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
