Compact Disc (CD) Illustration - Digital Media Storage Icon #83610 (License: Personal Use)

This image displays a standard 120mm compact disc (CD), featuring a metallic silver data layer that diffracts light into a rainbow spectrum when illuminated. The central hub contains clamping holes for drive compatibility, and the disc’s polycarbonate substrate protects the encoded pits and lands beneath the reflective aluminum layer. CDs revolutionized consumer media in the 1980s-2000s for music, software, and archival storage.
