A single-sided double-layer DVD one-time recordable disc with a storage capacity of 8.5 GByte has been developed for the first time. The disc format is designed for maximum compatibility with existing DVD players and DVD read only drives. The physical format of the DVD+R double-layer disc is described in detail. Physical parameters, compatibility, double-layer effects and margins are discussed. At the end a short description of the logical format is given.
