Explanation
A disc is an object that's round and flat. It might be a toy that you throw, like a Frisbee, or it might be a compact disc with digitally encoded music. Disc is often used interchangeably with disk. A disc galaxy, or disk galaxy, is a vast collection of stars that appears flat and circular through a telescope. The discs, or disks, in your spine are circular pads of cartilage that cushion the vertebrae. But the disc spelling is more commonly used for a phonograph record on which music is inscribed and played back on a record player. And a disc jockey entertains people by playing recorded music, originally that which was recorded on discs.
