Explanation

Comparing optical and magnetic storage media by capacity: Floppy diskette holds ~1.44 MB; CD-ROM holds ~700 MB; DVD holds ~4.7 GB (single-layer) or ~8.5 GB (dual-layer); Blu-ray holds ~25 GB (single-layer), ~50 GB (dual-layer), and up to 100 GB or more with BDXL format. Blu-ray achieves its higher density by using a shorter-wavelength blue-violet laser (405 nm) compared to the red laser used in DVDs, allowing data to be packed more tightly on the disc.
