About these units
Megabyte (MB)
A megabyte is traditionally 1,048,576 bytes (2²⁰), though storage manufacturers sometimes use the decimal version of 1,000,000 bytes. Throughout the 1980s and 1990s, megabytes represented substantial storage: early PCs had 256 kB or 512 kB of RAM, and hard drives with 10–40 MB were considered spacious. Software developers worked within tight memory budgets, optimizing every byte. Megabytes remain relevant today for file sizes such as images, audio files, small binaries, and executable programs. They mark a transitional era when computing moved from kilobytes to the far larger storage capacities we now expect.
CD (80 minute) (CD (80 min))
The 80-minute CD expanded storage to 700 MB, offering a modest but meaningful increase over the 74-minute version. This capacity became the industry standard for audio production, software, and media distribution. The slightly denser data-spacing required careful calibration but proved reliable for most computer and consumer hardware. For many users, CD-R and CD-RW discs became a primary means of personal backups, music burning, and long-term storage before USB drives became widespread.
