Can DVD drives read CD-Rs?
(1999/09/12) The only discs that a DVD drive 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. Some DVD players come with two lasers so that they can read CD-R. CD-RW discs have a different formulation, and may work even on players that can’t handle CD-R media. Some DVD drives may be unable to read multisession discs. If the box doesn’t say that something is supported, assume that the feature isn’t. Look for the MultiRead logo, which indicates that the DVD player can read all existing CD formats, including CD-ROM, CD-DA, CD-R and CD-RW. [ I verified that the Sony DVP-S3000 can read CD-R media, though the manual didn’t say anything about them. It plays audio CDs and VideoCDs off CD-R just fine.
