Optical Storage DevicesOptical-Storage-Devices-Revision-Sheet Optical Storages used to be incredibly popular up until the last couple of years where cloud storage and the rise of video and game streaming services have massively reduced their popularity. Types of optical storage devices:
Optical storage devices offer cheap and portable high capacity secondary storage. Far more portable than an internal hard-drive, which makes them good for small / medium size backups and great for sending through the post. How they workOptical storage devices work by firing a laser at the surface of a spinning disk. The disc is covered in a pattern of pits in the CD surface. As the laser hits the pits it is reflected and the pattern of pits it detected by a laser detector. Solid State StorageSolid State Storage DevicesSSD Drive – Expensive but fast Solid-State-Devices-Revision-Sheet Solid state devices are the newest form of storage to emerge. The technology is used in Hard Drives, SD Cards and USB sticks. Solid state storage devices work by storing data in flash chips electronically. They are still more expensive than traditional storage devices but the price per GB is falling all the time. Advantages

Difference Between Magnetic Disk and Optical Disk:. Why are optical storage media considered better than magnetic storage media?Optical storage provides greater memory capacity than magnetic storage because laser beams can be controlled and focused much more precisely than can tiny magnetic heads, thereby enabling the condensation of data into a much smaller space.
Which one is the magnetic and optical memory?Optical Storage Devices:
Optical storage devices are flat, round disks which spins around its center. The difference with magnetic storage devices is that in optical storage devices LASER light is used to read and write data in disks. Examples are CD, DVD etc.
What is a magnetic storage device?A magnetic disk is a storage device that uses a magnetization process to write, rewrite and access data. It is covered with a magnetic coating and stores data in the form of tracks, spots and sectors. Hard disks, zip disks and floppy disks are common examples of magnetic disks.
