What kind of data does optical storage primarily deal with?

Optical storage primarily deals with permanent files. This type of storage medium, including CDs, DVDs, and Blu-ray discs, is designed to store data long-term. Once data is written to an optical disc, it remains there until it is intentionally erased or the disc itself is damaged.

This permanence makes optical storage ideal for archiving purposes, such as storing music, movies, software, and important documents. Unlike temporary files, which are often lost when a system shuts down or programs are closed, optical storage retains data without needing power. The characteristics of optical storage differentiate it from other types, such as volatile memory that only holds data temporarily, or live streaming data, which involves data that is transmitted in real-time rather than stored. Similarly, mobile application data can be stored on various platforms, but optical storage's primary function is not to handle that type of data in a temporary or live context.
