About these units
CD (74 minute) (CD (74 min))
A 74-minute CD typically holds 650 MB of digital data. Originally designed for audio playback, CDs later became a major format for software distribution, backups, and digital media. The 74-minute length was chosen to accommodate Beethoven's Ninth Symphony on a single disc—a blend of engineering, commerce, and cultural symbolism. As CDs pivoted to data storage (CD-ROM), their precise reflectivity patterns and error-correction codes allowed reliable long-term archival. These discs became essential for installing software, distributing games, and storing personal files throughout the 1990s and early 2000s.
DVD (2 layer, 1 side) (DVD (2L, 1S))
A dual-layer, single-sided DVD stores 8.5 GB using a semi-transparent layer that allows the laser to focus at two depths. This innovation enabled longer movies, higher-quality video, and special editions packed with supplemental content. Dual-layer DVDs became standard for commercial video distribution and professional data storage. Although burning DL DVDs at home was initially slow and expensive, they played a crucial role during the transition to higher-capacity optical storage.
