Storage Devices

Optical Storage

Optical storage is recorded and stored by making marks in a pattern that can be read with the aid of light, most commonly a laser precisely focused on a spinning disc.



Examples of optical storage are CD, DVD and Blueray.

Magnetic Storage

Magnetic storage uses different patterns of magnetization to store data in a non-volatile fashion.


Examples of magnetic storage are floppy discs and credit card strips.


Solid State Storage

A solid state drive is a storage device that cannot be changed physically and is made up of a circuit.
