Question and answer
CD R and DVD R advantages and disadvantages?
The advantages to CDRs are : Can read discs made by different CD-R and CD-RW devices CD-RW’s media can be written/erased over and over CD-RW devices can write to both CD-R and CD-RW media. The disadvantage to CDRs are: Increased overhead – less [ usable space due to the multiple table of contents, fixed or variable length packets CD-RW drives are slower than CD-R drives by 2X Backward computability issues due to lower emulation of the pits and lands Areas can get burned out DVD-R is the most compatible format and can be read by practically all DVD players. They can be read by DVD
drives in computers, portable DVDs and home DVD players. They cost a little less than DVD+R, and are significantly cheaper than RW DVDs. The dual layer versions offer almost twice the storage of rewritable discs, which is a further saving of both money per disc and the number of discs required. The major drawback to DVD-Rs is that they can only be written to once. Most people prefer to put routine system backups and temporary files onto a rewritable disc, which can be rewritten up to about 1,000 times. The other minor disadvantage is that although you can read a DVD-R with either a - R or +R drive you can only write to it with a -R type drive. This is not really a problem as all modern drives are compatible with both systems. ]
