Your CD-ROM disc is vibrating in the CD-ROM drive.
m Some CD-ROM disc labels have artwork that is noticeably thicker on one
side than the other, which 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. The vibration damages neither the
CD-ROM disc nor the computer and occurs with very few CD-ROM discs.
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.
If you use a CD-ROM disc with a removable (sticky) label, remove the
label before inserting the disc.
Your computer ejects a CD-ROM disc without giving you any error message.
m Make sure the disc is flat in the tray and the disc label is facing up. If
you’re using a small (8 cm) disc, make sure it’s centered within the tray’s
inner ring.
m The disc may need to be cleaned. (See “Handling Compact Discs” in
Appendix A.) If there are visible scratches on the shiny side of the disc,
you may be able to remove them with a CD polishing kit (available from
your audio CD dealer). If the scratches can’t be removed, you’ll need to
replace the disc.
m The disc may be damaged. Try another disc in the drive, and try the
original disc in another drive. If the original drive reads other discs or if
the original disc doesn’t work in another drive, the disc is probably
damaged. You’ll need to replace the disc.
You can’t open a document on a CD-ROM disc.
m Try opening the application program first; then open the document.
m Read the manual that came with your CD-ROM disc. Some discs come
with software that you need to install on your computer before using
the disc.
You can’t save changes you make to information on a CD-ROM disc.
CD-ROM is a read-only medium. This means that information can be read
(retrieved) from it, but not written (stored) on it. You can save the changed
information on a hard disk or floppy disk.
