A disk changer employs two disk guides to support a recorded disk at opposite points along its edge. One of the disk guides has a belt that revolves around two pulleys. A surface of the belt frictionally engages an edge surface of the disk. The other disk guide has two surfaces, a low-friction guide surface parallel to the recorded surface of the disk and a resilient sloped surface that forms an angle with both the recorded surface of the disk and the perpendicular to the recorded surface of the disk. Both guides are urged together, and, as a result, the sloped surface is urged against the disk edge. Because of the slope of the surface, the sloped surface meets a corner where the recorded surface of the disk meets the edge surface of the disk and urges the disk's recorded surface toward the guide surface. This stabilizes the disk against pitching motion.
