CD-R Media refer to CD ROM Recordable/CD-ROM ReWritable. It can be used to record data or audio for later play back in CD players or computers. The capacity is 700MB or around 80 minutes. CD-R could only be used once while CDRW could have repeat uses.
good news about CD-R media that (at the moment) you can record them quicker than DVD-R media. At their maximum speed of 52x, you can burn a CD in 90 seconds. So if speed is a value to you, and you don’t mind the 700MB/80min of disc capacity, burn your music, video, and data in CD-R discs. A regular CD Rom will not be able to record on CD-R. You will need a CD recorder. Most DVD recorders can burnCD-R media at 52x. 

CD-Rs may be old school with the advent of DVD media, but for burning audio, it’s still the media of choice, in that it can play in the modern media players and the old CD players.

Dual Layer Media (DVD-R DL) or Double Layer Media (DVD+R DL) (called by the RW Alliance), means that much like commercially pressed DVD-ROMs, these recordable discs have two layers of dye, almost doubling the size of older DVD5 format to 8.5GB. This is a recordable DVD9 format.
Note that not all DVD burners have the ability to record in the Double/Dual Layer format. If you are shopping for a DVD burner that supports this format, make sure that it is explicitly stated. If your currently own a DVD burner does not have this capability, it is possible to be upgraded to burn Double/Dual Layer media via a firmware update. Please check with your DVD burner manufacturer for additional details.
 

Developed by the corporations of the DVD+RW Alliance the DVD+R format has advanced editing and operational capabilities. The DVD+RW Alliance includes Philips, Sony, HP, Verbatim, and so forth.
Modern DVD players and DVD drives are hybrids, capable of player and/or recording both DVD-R and DVD+R media. With a DVD+R capable player, you can take advantage of the DVD+R double layer technology, in which you can read 8.5 GB on a single side DVD+R DL disc. Burning a DVD+R DL disc, however, requires a DVD+R DL media compatible burner.
