On a digital video disc (DVD), video and audio data are stored in a series of tiny pits that are evenly spaced along a long spiral that traverses most of the surface of the disc. The scanning laser in a DVD player must read this information at a constant rate. As the player reads information recorded closer and closer to the outer edge of the DVD, the disc should:. a. rotate faster.
b. rotate slower.
c. rotate at the same speed.
