    • CD-R (CD-Recordable) - CD-R allows data to be stored on a CD, but only once. It is ideal for the backing up of data or for storing digital music.
    • CD-RW(CD-Rewriteable) - A CD-RW disk allows data to be stored on the disk over and over again. Transfer rate is less and the time taken to locate a file is greater than a hard drive. The media is not as robust as a hard drive.
    • DV-RAM(Digital Versatile Disk - Random Access Memory) - DVD-RAM drives allow repeated storage and erasure of data so they act a bit like a hard drive but the disks cannot be used with all DVD drives.
