magnetic storage

Magnetic storage is a type of data storage that uses magnetic fields to record and retrieve information. Common examples include hard disk drives (HDDs) and magnetic tape. In these devices, data is saved on coated surfaces that respond to magnetic charges. When writing data, the device alters the magnetic orientation of tiny areas on the surface, representing the information. When reading, it detects these magnetic patterns. Magnetic storage is popular for its ability to hold large amounts of data at relatively low cost, making it suitable for everything from personal computers to enterprise data centers.
