Pioneer demonstrated a mock-up (prototype) drive for double-layer recording. The company is currently developing its technology for writing on two layer DVD media but the implementation in hardware is expected by the end of 2004, where the DVD-Forum is expected to approve Pioneer's proposal.

A pre-recorded dual layer DVD-R disc was played back on an unmodified DVD player, demonstrating layer switching and playback of video content coming from both layer 1 and 2. Below you can see the recorded Dual Layer DVD-R (8.5GB, 2x). The disc was made by MKM, as in the case of the +R9 format.
