Magnetic memory refers to a type of data storage technology that uses magnetic materials to record and retrieve information. This method is commonly found in devices like hard disk drives (HDDs) and magnetic tapes, where data is stored in the form of magnetic fields. The ability to read and write data magnetically allows for efficient and reliable storage solutions. One of the key advantages of magnetic memory is its capacity to store large amounts of data at a relatively low cost. Unlike solid-state drives (SSDs), which use flash memory, magnetic memory can offer higher storage capacities, making it suitable for applications that require extensive data retention, such as data centers and archival storage.
