Using CDs and DVDs
Your computer might have a DVD ROM drive or recordable DVD drive installed. DVD drives use
industry-standard, 12 cm (4.75-inch) CD media or DVD media. If your computer comes with a DVD drive,
the drive can read DVD-ROM discs, DVD-R discs, DVD-RAM discs, DVD-RW discs, and all types of CDs,
such as CD-ROM discs, CD-RW discs, CD-R discs, and audio CDs. If you have a recordable DVD drive,
it can also record on DVD-R discs, DVD-RW discs, type II DVD-RAM discs, CD-RW standard and high
speed discs, and CD-R discs.
Follow these guidelines when using the DVD drive:
• Do not place the computer in a location where the drive is exposed to the following:
– High temperature
– High humidity
– Excessive dust
– Excessive vibration or sudden shock
– An inclined surface
– Direct sunlight
• Do not insert any object other than a CD or DVD into the drive.
• Before moving the computer, remove the CD or DVD from the drive.
Handling and storing CD and DVD media
CD and DVD media are durable and reliable, but they do require some care and special handling. When
handling and storing a CD or DVD, follow these guidelines:
• Hold the disc by its edges. Do not touch the surface of the side that is not labeled.
• To remove dust or fingerprints, wipe the disc with a clean, soft cloth from the center to the outside. Wiping
the disc in a circular direction might cause loss of data.
• Do not write or stick paper on the disc.
• Do not scratch or mark the disc.
• Do not place or store the disc in direct sunlight.
• Do not use benzene, thinners, or other cleaners to clean the disc.
• Do not drop or bend the disc.
• Do not insert damaged discs into the drive. Warped, scratched, or dirty discs can damage the drive.
