David Gregg was the inventor of the optical disk.
The effect of decreasing incubation time on optical density is that optical density decreases. Incubation time and optical density have a proportional relationship.

An Optical Disk
it is a CD(Compact Disk) and a DVD (Digital Video Disk)
no,harddisk is not an optical storage
an optical disk which stores data optically

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.
