2-13] Can DVD players read CD-Rs?

(2001/11/28)

The only discs that a DVD player is guaranteed to read are DVD discs.
Support for CD-ROM, CD-R, and CD-RW may be included, but is by no means
guaranteed.

CD-R was designed to be read by an infrared 780nm laser. DVD uses a
visible red 635nm or 650nm laser, which aren't reflected sufficiently
by the organic dye polymers used in CD-R media. As a result, many DVD
players can't read CD-R media. Some DVD players come with two lasers so
that they can read CD-R. For a technical discussion, see
http://www2.osta.org/osta/html/cddvd/intro.html and
http://www.emedialive.com/EM1998/bennett3.html.

CD-RW discs have a different formulation, and may work even on players that
can't handle CD-R media. If CD-R media doesn't work, try copying the
disc to CD-RW instead (assuming your recorder supports CD-RW).

Some DVD-ROM drives may be unable to read multisession discs. In general,
though, DVD-ROM drives (as opposed to DVD players) are able to read
CD-R media.

If the box doesn't say that something is supported, assume that the
feature isn't. Look for the MultiRead or MultiPlay logos, which indicate
that the DVD player or DVD-ROM drive can read CD-R and CD-RW.
