Hard disk drives (HDDs)

Magnetic recording devices mounted in computers and the like. A magnetic field is generated in the recording head, this generates magnetization in the magnetic bodies on the recording medium, and this records digital signals. Rare earth magnets are used in spindle motors for rotating the recording medium, voice coil motors (VCMs) for driving the magnetic head, etc.
