A hard disk drive (HDD, or also hard drive or the now-obsolete usage hard file) is a non-volatile data storage device that stores data on a magnetic surface layered onto hard disk platters.
Mechanics and magnetics
A hard disk uses rotating platters (disks) to store data. Each platter has a smooth magnetic surface on which digital data is stored. Information is written to the disk by applying a magnetic field from a read-write head that flies very close over the magnetic surface. The magnetic medium (film) on the disk surface changes its magnetization in microscopic spots (bits) due to the head's write field. The information can be read back by a magnetoresistive (MR) read sensor which is part of the same head structure on the trailing end of the flying slider. The read sensor detects the magnetic flux emanating from the bit transitions passing underneath it through a small change of the MR sensor's electric resistance.

@RichardBuckle I'm positively awash in hard drives, actually. I just hate to lose the nice expensive one that can record in real time.

@mariancall Reluctant hard drives not good. Get an external drive to backup & cross your fingers. Last drive died on me in less than a week.
