Oct 10, 2024 · Paper, Microfilm/Microfiche, and Optical Media. Magnetic Media and Solid State media are only viable as “short term” backup or storage as they are too fragile.
Optical storage refers to a class of data storage systems that use light to read or write data to an underlying optical media. Although a number of optical formats have been used over time, the most common examples are optical disks like the compact disc (CD) and DVD.
An optical disk is an electronic data storage medium that can be written to and read from using a low-powered laser beam. Most of today's optical disks are available in three formats: compact disks ( CDs ), digital versatile disks (DVDs) -- also referred to as digital video disks -- and Blu-ray disks, which provide the highest capacities and ...
Sep 27, 2023 · CDs, DVDs, and Blu-rays are the most common optical media formats, and are often used to distribute music, videos, games, and other software. Instead of storing data using magnetic charges, optical media encodes digital data using a series of bumps and pits on the underside of a disc's metallic coating.
