Optical Discs
Optical discs are a type of storage media that use laser technology to read and write data. They are typically made of polycarbonate and have a reflective layer that stores data in the form of tiny pits and lands. Optical discs come in various formats, including CD, DVD, and Blu-ray, and can store different amounts of data depending on the format and the number of layers. Optical discs are widely used for storing and distributing digital content, such as music, movies, and software. They are also used for data backup and archival purposes, as they offer high durability and long-term data retention. However, optical discs have largely been replaced by digital storage solutions, such as cloud storage and solid-state drives, due to their limited storage capacity and slower read and write speeds.
