enjoyment from your CD collecti on and player.
zDo not write on either side of the disc, particularly the non-label side from which
signals are read. Do not mark this surface.
zKeep your discs away from direct sunlight, heat, and excessive moist ure.
zAlways hold the CDs by the edges. Fingerprints, dirt, or water on the CDs can
