Magneto-optic storage devices are data storage systems that combine magnetic and optical technologies to read and write information. They use a laser to heat a small area of a magnetic material, allowing the magnetic state to be changed. This process enables the storage of data in a way that is both stable and retrievable. These devices are known for their durability and long lifespan, making them suitable for archival purposes. They can store large amounts of data and are often used in applications where data integrity is crucial, such as in data centers and scientific research.
