spinning disks

Spinning disks, or hard drives, are storage devices that use rapidly rotating disks coated with magnetic material to store data. A read/write head moves over the spinning surface to access or record information, similar to how a record player needle reads music from a vinyl record. The rotation and magnetic properties enable quick data retrieval and storage, making hard drives reliable for saving large amounts of information. Their efficiency depends on the speed of rotation (measured in RPM) and the density of data stored on each disk surface.
