Beyond Blu-ray Disc[edit]
The Holographic Versatile Disc (HVD), described in the ECMA-377 standard, has been in development by The Holography System Development (HSD) Forum using a green writing/reading laser (532 nm) and a red positioning/addressing laser (650 nm). It is to offer MPEG-2, MPEG-4 AVC (H.264), HEVC (H.265), and VC-1 encoding, supporting a maximum storage capacity of 6TB.[65] No systems corresponding to the Ecma International HVD standard have been released.[66] Because the Blu-ray Disc format is upgradable it poses challenges to the adoption of the HVD format.
Currently, 4K Blu-ray Disc is to become available towards the end of 2015. With the advent of 8K resolution and full dome 8192×8192 requirements, however, it is unknown whether Blu-ray Disc can support any resolution higher than 4k 4096x2160 or can scale to meet not only those challenges, but also the expectations of Virtual Reality for multiple 12K or QUHD (Quad Ultra HD) 15360x8640 images at 120 frames per second.[67]
