CD-R means you can only write/record files to a CD/DVD one time. CD-RW means you can write/record files to a CD/DVD and then re-write new files or delete old files from the said CD-RW. CD-RW hold less than CD-R's and they tend to get buggy the more times you add/edit/delete/re-write over them. Also if you are lets say burning music to a CD to play in your car or something some CD-RW's are not really compatible with standard car stereos.
Yes it Can Also cd rw and dvd r and dvd rw can also
Cd-R or Cd-RW
Newer cars can play almost any CD. Many older cars have players that will not play CD-R or CD-RW. If your CD player and the user manual do not show the CD-R, CD-RW, or MP3 logos, you probably will not be able to play anything but factory recorded music.
A CD-RW drive is able to Read CDs, VCDs, and write CD-R and CD-RW.
Most likely, your computer is not a CD-RW burner, so it can play it, but not edit things on it. My suggestion, put it into a CD-RW burner or DVD Player with burner, then try again.
A CD-RW is a CD disc that can be re-recorded. Whether or not you can play it on your CD player is determined by two things. If you use software to create an audio CD on a CD-RW then it will play on most normal CD players. If you have a CD player that will play MP3 discs as well as audio CD's, you can copy the tracks from your computer onto your CD-RW disc as MP3 files and again it will play. This type of disc will not play in a normal audio CD player without MP3 capability. Because MP3 files take up so much less space on a CD than normal audio tracks, an MP3 disc has the advantage of being able to hold massively more tracks than a normal audio CD.
there really wouldn't be a problem, the only problem you might encounter is the fact that an old CD-ROM might not play CD-r's and CD-rw's depending on how old the drive is.
