Magnetic storage devices are tools used to store digital data using magnetic fields. Common examples include hard disk drives (HDDs) and magnetic tapes. These devices work by magnetizing tiny particles on a surface to represent data, allowing for the retrieval and writing of information. These devices are popular due to their ability to store large amounts of data at a relatively low cost. While they are slower than some modern storage options like solid-state drives (SSDs), magnetic storage remains widely used for backups and archiving because of its durability and capacity.
