Using specialized software, the drive reads the disc at low, stable speeds. The software extracts the data tracks (usually saved as a .bin file) and the structural layout of the disc (saved as a .cue file). 3. Verification via Cryptographic Hashes

Unlike solid-state cartridges, optical media (CDs, DVDs, Blu-rays) is fragile and finite. The data layer on a disc is an incredibly thin piece of aluminum sandwiched between layers of plastic.
