c There may be condensation in the drive or the disc.
Remove the disc and allow the unit to stand for
approximately one hour.

c When the drive is operating, the personal computer may

c As a rule, it takes more time to read a CD-RW than it does
a CD-R or CD-ROM. There are also major differences
between disc formats, which may also affect reading time.
c You may not be able to read a CD-R or CD-RW disc not
prepared on this drive, or you may need to further process
the disc on the personal computer that created the disc. For
details, refer to the manuals provided with the device used
to write data to the CD-R or CD-RW disc.
c The read speed of CD-RW discs is slower than DVD+R,
DVD+RW, DVD-R, DVD-RW, and CD-R discs.
Therefore, you may not be able to play back some high-
quality MPEG2 data. In this case, copy the data to the hard
disk, or write the data to DVD+R, DVD+RW, DVD-R, or
DVD-RW, and then play back the data.
c Music CDs created using CD-RW can only be played back
on a CD player supporting CD-RW playback.
