In a few moments, an icon for the CD-ROM disc appears on your screen.
If your CD-ROM disc vibrates in the CD-ROM drive
Some CD-ROM disc labels have artwork that is noticeably thicker on one
side than the other and can cause the disc’s weight to be slightly off-center.
This uneven distribution of weight coupled with the high rotation speed of
your CD-ROM drive can cause some discs to wobble in the drive and make
your computer vibrate. Although this occurs infrequently, you should be
aware of it in case it does. The vibration damages neither the CD-ROM disc
nor the computer. If you can feel or hear that the CD-ROM disc is vibrating
in the computer, you don’t need to do anything special; continue to use the
CD-ROM disc as you normally would.
Note: If you use a CD-ROM disc with a removable (sticky) label, remove the
label before inserting the disc.
