👉 DVD fluid, or DVD-RW (Rewritable) disc material, is a complex mixture of organic compounds designed to store digital data on a DVD. It primarily consists of polycarbonate plastic, which forms the disc's base, and a layer of reflective metal particles, typically aluminum or gold, embedded within this plastic. The data is encoded onto the disc using microscopic pits and lands (flat areas) that represent binary information; when a laser reads the disc, it detects these changes in reflectivity to interpret the data. DVD fluid also includes dyes or other organic compounds that help in the creation of the pits and lands, ensuring the disc can be written to and read multiple times, making it a versatile medium for storing various types of digital content.
