Disk or Disc?

Which terminology is correct: Hard “Disk” Drive (HDD) or Hard “Disc” Drive? Is it a compact “disk” or “disc”?

The answer is that if light is used to read the data, then the correct word is “disc” as in Compact Disc or Digital Versatile/Video Disc (DVD). Your hard disk doesn’t use light to read the data. The data is read by detecting the magnetization of the material in the platter; so it is a “disk”.
