answer the questions?!?!?!?!?!?!?!?!?!?!?!?!?!?! stupid people!-.-
Yes, optical disks use a laser beam to read and write data on the disk. The laser beam is focused onto the surface of the disk to detect and interpret the patterns of pits and lands that represent the data stored on the disk.
Which of the following is an example of optical? Ram flash card compact dise disk drive Answer this question…
Examples of coherent sources include lasers, superluminescent diodes, and optical fibers. These sources produce light waves that are in phase with each other, leading to interference patterns and constructive interference.
Some examples of visible light being utilized in real life applications include photography, microscopy, barcode scanners, and optical communication systems.
Some examples of things that use light energy include solar panels, light bulbs, photovoltaic cells, and optical fibers.
David Gregg was the inventor of the optical disk.

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
An optical drive, or more accurately an optical disk drive (ODD) is medium for storing digital data. Examples are CD, DVD and blu-ray. The characteristic of an optical drive system is that beams of light (typically laser) are used to read the medium.

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.
There could be several reasons why your optical disk is not reading. Common issues include a dirty or scratched disk, a malfunctioning optical drive, or compatibility problems with the disk format. Additionally, outdated or missing drivers for the optical drive can also prevent it from reading disks properly. Checking these factors can help identify and resolve the issue.
