optical disk storage are read only so they cannot get infected. But if you burn files which are infected by viruses then the optical disks can spread the virus
use a laser to read and write data. Optical disks have very large storage capacity but they are not fast as hard disks. There are three basic types of optical disks: CD-ROM, WORM and erasable. DVD-ROM is higher- capacity disc
