What else can I help you with?
Does optical disk use laser beam?
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?
Which of the following is an example of optical? Ram flash card compact dise disk drive Answer this question…
What are examples of coherent sources?
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.
What are some examples of visible light being utilized in real life applications?
Some examples of visible light being utilized in real life applications include photography, microscopy, barcode scanners, and optical communication systems.
What things do you use that has light energy in it?
Some examples of things that use light energy include solar panels, light bulbs, photovoltaic cells, and optical fibers.
Who invented the optical disk?
David Gregg was the inventor of the optical disk.
What type of media is a hard disk?

What is an optical storage medium such as a CD or DVD?
An Optical Disk
What is a optical disk?
it is a CD(Compact Disk) and a DVD (Digital Video Disk)
Is disk drive an example of optical storage?
no,harddisk is not an optical storage
What is an optical disks?

What do you call the subdivision of a track on magnetic disk or optical disk?
A sector
What is a type of optical storage media that consists of a flat round portable disk made of meta plastic and lacquer?
Optical disk
What purpose do optical drives serve?
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.
Are there Virus that can affect an optical disk storage?
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
What are the limitations of optical disk?
(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.
What part of the computer reads an optical disk?
The disk drive
