About these units
DVD (2 layer, 2 side) (DVD (2L, 2S))
The dual-layer, double-sided DVD provides the maximum DVD capacity: 17.1 GB. With two layers on each side, these discs offered exceptional storage for large software packages, high-definition video masters (before Blu-ray), and professional archival applications. However, they were rarely used in consumer markets due to cost, complexity, and the inconvenience of double-sided handling. They remain an interesting pinnacle of DVD engineering—pushing the medium to its physical limits.
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.
