CD-R discs

CD-R (write-once) discs are widely used for creating a permanent copy of data that can be shared as
needed. 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.

LightScribe DVD+R discs

Use LightScribe DVD+R discs for sharing and storing data, home videos, and photos. These discs
are read-compatible with most DVD-ROM drives and DVD video players. With a LightScribe-enabled
drive and LightScribe software, you can write data to the disc and then add a designer label to the
outside of the disc.

Blu-ray Disc

Also called BD, Blu-ray Disc is a high-density optical disc format for the storage of digital information,
including high-definition video. A single-layer Blu-ray Disc can store 25 GB, over five times more than
the 4.7-GB single-layer DVD. A dual-layer Blu-ray Disc can store 50 GB, almost 6 times more than
the 8.5-GB dual-layer DVD.
