Magnetic storage is a method of saving data using magnetic materials. It works by altering the magnetic properties of a medium, such as a hard disk drive or a magnetic tape, to represent information. When data is written, tiny magnetic regions on the surface are aligned in specific patterns, which can later be read by a device. Common examples of magnetic storage include hard disk drives (HDDs) and magnetic tapes. These devices are widely used for storing large amounts of data due to their cost-effectiveness and capacity. However, they are generally slower than solid-state drives (SSDs), which use flash memory instead.
