Magneto-optical recording is a data storage technology that combines magnetic and optical methods to read and write information. It uses a laser to heat a small area of a magnetic material, allowing the magnetic properties to change. This process enables the recording of data in a way that can be read by a laser. The main advantage of magneto-optical recording is its ability to provide high data density and durability. Unlike traditional magnetic storage, it is less susceptible to data loss from environmental factors, making it a reliable option for long-term data preservation.
