Selecting the right disc

An optical drive supports optical discs (CDs and DVDs). CDs, used to store digital data, are also used
for commercial audio recordings and are convenient for your personal storage needs. DVDs are used
primarily for movies, software, and data backup purposes. DVDs are the same form factor as CDs but
have at least 8 times the storage capacity.
NOTE:
The optical drive on your computer may not support all the types of optical discs discussed in
this section.

CD-R discs

Use CD-R (write-once) discs to create permanent archives and to share files with virtually anyone.
Typical uses include the following:
Distributing large presentations
Sharing scanned and digital photos, video clips, and written data
Making your own music CDs
Keeping permanent archives of computer files and scanned home records
Offloading files from your hard drive to free up disk space
After data is recorded, it cannot be erased or written over.

CD-RW discs

Use a CD-RW disc (a rewritable version of a CD) to store large projects that must be updated frequently.
Typical uses include the following:
Developing and maintaining large documents and project files
Transporting work files
Making weekly backups of hard drive files
Updating photos, video, audio, and data continuously
DVD±R discs
Use blank DVD±R discs to permanently store large amounts of information. After data is recorded, it
cannot be erased or written over.
DVD±RW discs
Use DVD+RW discs if you want to be able to erase or write over data that you saved earlier. This type
of disc is ideal for testing audio or video recordings before you burn them to a CD or DVD that cannot
be changed.
