DVD+R is a type of optical disc used for storing data, including videos, music, and software. It is a recordable format, meaning users can write data onto the disc once, but cannot erase or rewrite it. DVD+R discs typically hold up to 4.7 GB of data, making them suitable for single-layer recordings. The DVD+R format was developed to compete with other recordable formats like DVD-R. It offers better error correction and compatibility with a wider range of players and drives. DVD+R discs are commonly used for personal backups and home video projects.
