what CD that allows you to read and write
CD-R
CD-R
That is a DVD burner. Most read and write to CDs as well as DVDs. Hybrid drives that read/burn CDs but only read DVDs also exist.
output device
A CD-RW drive is able to Read CDs, VCDs, and write CD-R and CD-RW.
First Answer:Sadly, you can't.Second Answer:Actually, most disc drives are backwards compatible to the last disc. So, DVD drives can read/write to CD and Blu-ray drives can read/write DVD and CDRs.It does not work the other way around. You can't read/write to a DVD if the drive is marked as a CD drive.
CD-ROMS
I would just replace the drive. Inside your drive there are two lasers. A write laser and a read laser. Your read laser has probably burned out so getting a whole new drive should do the trick. You can get a standard 52x/52x (read/write) CD-ROM/R/RW for about $35.
CD+r means write once, read many. This means that you can only write data to the CD once, after that it will be on there forever and you can always get to it.
CD-R is Compact Disk - Read CD-RW is Compact Disk - Read, Write
In general, no. CD-ROM is read-only. You can only read from it after a manufacturer writes to the disc permanently. However, there are recordable CDs (CD-R), which allow you to write once. And, there are rewritable (CD-RW), which allow you to write and erase many times. The same goes for existing DVD technology (DVD, DVD-R, DVD-RW).
This was mainly used to distinguish between different kinds of CDs, the (factory manufactored) read-only CDs, the recordable (write once) CDs and the re-writeable CDs.'Read-Write CD Rom' usually refers to the last kind. Formally it's a misnomer, since ROM (read only memory) would exclude writing, but since CD-ROM was initially the most common kind, many people referred to CDs as CD-ROMs and then added distinguishing modifiers like 'read-write' without realizing the specific meaning of the ROM acronym.(The same applies to read-write CD-ROM drives, named that way to distinguish them from read-only CD drives.)
