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 ...
Over the years, optical media have taken a variety of forms, including LaserDisc (LD), HD-DVD, write-once, read-many (WORM) optical cartridges and several others. From this mix, three formats have emerged as standards in today's optical storage market: Compact disk (CD). The CD represents the first generation of commercial optical storage.
An optical drive is a type of computer hardware that allows users to read and write data on optical discs such as CDs, DVDs, and Blu-ray discs. It utilizes laser or visible light technology to access the information stored on these discs.
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.
This article compares the technical specifications of multiple high-definition formats, including HD DVD and Blu-ray Disc; two mutually incompatible, high-definition optical disc formats that, beginning in 2006, attempted to improve upon and eventually replace the DVD standard.
