Optical Storage
Optical storage is a data storage technology that uses lasers to read and write data on optical discs, such as CDs, DVDs, and Blu-ray discs. It works by encoding information as microscopic pits and lands on a reflective surface, which are interpreted as binary data. This technology was widely used for distributing software, media, and backups due to its portability and durability.
Developers should learn about optical storage for historical context, legacy system maintenance, and understanding data storage evolution. It's relevant when working with archival systems, media distribution, or retro computing projects where optical discs are still in use. Knowledge is also useful for data recovery from old backups or understanding physical storage limitations.
