David Gregg was the inventor of the optical disk.
The optical disk was invented in 1958 by David Paul Gregg. He created a system called the Laser Optical Storage System (LOSS) that used a laser beam to record data onto a transparent disc.
The compact optical disk was invented by James Russell in 1965

it is a CD(Compact Disk) and a DVD (Digital Video Disk)

who invented the optical carrier bus?
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.
