● 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 Discs (BDs)
BD 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 5 times the storage capacity of a single-layer
DVD at 4.7 GB. A dual-layer Blu-ray Disc can store 50 GB, almost 6 times the storage capacity of a
dual-layer DVD at 8.5 GB.
Typical uses include the following:
● Storage of large amounts of data
● High-definition video playback and storage
● Video games
NOTE: As Blu-ray is a new format containing new technologies, certain disc, digital connection,
compatibility and/or performance issues may arise, which do not constitute defects in the product.
Flawless playback on all systems is not guaranteed.
Playing a CD, DVD, or BD
1. Turn on the computer.
2. Press the release button (1) on the drive bezel to release the disc tray.
