Uncover various types of optical storage devices, from common examples in computer science to both disc and non-disc storage options. Additionally, you will learn about the numerous advantages of optical storage in computer organisation, including its high storage capacity and performance, as well as its durability and reliability.
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.
This chapter provides a brief overview of optical storage principles and introduces three widely used types of optical disc. The following three chapters look at each one in more detail, in each case considering how logical data structures may be designed to exploit its physical characteristics effectively.
Optical storage, electronic storage medium that uses low-power laser beams to record and retrieve digital (binary) data. In optical-storage technology, a laser beam encodes digital data onto an optical, or laser, disk in the form of tiny pits. Learn more about optical storage in this article.
Learn about optical storage, any storage medium where data is written and read with a laser. Explore examples and history plus advantages and disadvantages.
26 lip 2022 · For example, the most common optical storage devices around are Compact Discs (CDs), Digital Versatile Discs (DVDs), and Blu-ray discs. Furthermore, CDs normally have a storage capacity of around 700 MB only. Meanwhile, DVDs with a single layer offer up to 4.7 GB of storage space, and multi-layered ones offer 8.5 GB.
