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
(a)- it is a read-only storage medium. Data once recorded, cannot be erased, and hence the optical disk cannot be reused. (b)- thd data access speed for optical disk is slower than magnetic disks; (c)- optical disk require a more complicated drive mechanism that magnetic disk.
