Hard drive it:

The store on hard magnetic drives or NZhMD (English hard (magnetic) disk drive, HDD, HMDD), the hard drive, in a computer slang "winchester" — the memory device (the device of storage of information) of random access based on printsipemagnitny record. Is the main store of the computers given in the majority.

Unlike a "flexible" disk (diskette), information in NZhMD registers on rigid (aluminum or glass) the plates covered with a layer of ferromagnetic material, most often a dvuokisikhroma — magnetic disks. In NZhMD one or several plates on one axis are used. The reading-out heads in an operating mode do not concern a surface of plates thanks to the layer of the running stream of air which is formed at a surface at fast rotation. The distance between a head and a disk makes several nanometers (in modern disks about 10 ^{nanometers [1]}), and lack of mechanical contact provides long service life of the device. In the absence of rotation of disks of a head are at a spindle or outside a disk in a safe zone where their emergency contact with a surface of disks is excluded.

Also, unlike a flexible disk, the data carrier is usually combined with the store, the drive and the block of electronics. Such hard drives are often used as a fixed data carrier.
