Most optical storage media can retain data for decades because they aren't subject to magnetic decay and leakage.

Question

Quizplus · Accepted Answer

Optical storage media uses lasers to read and write data, which means that the information is stored as tiny pits on the surface of the disc rather than using magnetic charges. Unlike magnetic storage media, optical storage is not subject to magnetic decay and leakage. Therefore, most optical storage media can retain data for several decades before the disc begins to degrade or become unreadable, making it a reliable and durable option for long-term storage.
