Pioneer showcased its high density multi-layer optical disc at the IT Month fair in Taipei, Taiwan. The optical disc uses the same protocol as that of the Blu-ray disc, except for that Pioneer perfected its material technology of reflective layers, that allows for 16 separate layers of 25 GB each on a single side of the disc. Blu-ray discs in production facilitate only two parallel layers making for a maximum of 50 GB storage space per disc. The 16 layers on Pioneer's disc would make for 400 GB.

The specifications of the pick-up head (PUH) of the disc is the same as those for the PUH of blank BD discs, and therefore the Pioneer discs can be read on any of the Blu-ray disc players in production, the company said. In its current form, the media is in a read-only (burn/press once) format, and could reach production anywhere between 2008 and 2010, with re-writable media slated for 2010~2012, and even denser 1 TB discs in 2013, according to the company's internal roadmaps.
