Heat Assisted Magnetic Recording (HAMR) is an advanced data storage technology that leverages nanotechnology to dramatically increase the storage density of hard disk drives (HDDs). HAMR uses a combination of thermal energy and magnetism to write information onto the disk. A small laser heats a tiny area of the disk, reducing the coercivity of the magnetic material, making it easier to change its magnetic state. Once cooled, the magnetic state remains stable, allowing for higher data density.
