A hard disk drive (HDD; also hard drive, hard disk, or disk drive) [2] is a device for storing and retrieving digitalinformation, primarily computer data. It consists of one or more rigid (Hence "hard") rapidly rotating discs (platters)coated with magnetic material, and with magnetic heads arranged to write the data to the surfaces and read it fromthem.

Hard drives are classified as non-volatile, random access, digital, magnetic, data storage devices. Introduced byIBM in 1956, hard disk drives have Decreased in cost and physical size over the years while DramaticallyIncreasing in capacity and speed.

Hard disk drives have been the dominant device for secondary storage of the data in general purpose computerssince the early 1960s. [3] They have maintained this position Because advances in their recording capacity, cost,reliability, and speed have kept pace with the requirements for secondary storage.
