Following Hitachi's annoucement of plans to hit 5TB in a single hard drive by 2010, Pioneer follows suit by proclaiming a major advancement in the optical storage arena with an unprecedented 16-layer optical disc capable of storing 400GB. Presumably intended for distribution as Blu-ray media, Pioneer points out the new disc's 25GB  per-layer capacity is the same as that of a Blu-ray disc (BD).

Cross-talk among multiple layers has been a stickling point in the optical industry, but Pioneer claims to have tackled the problem with a specialized disc structure designed to reduce interference from adjacent layers. And what about compatibility with existing Blu-ray players? Pioneer says that because the optical specifications of the lens are the same as those for existing BD discs, there shouldn't be any compatibility concerns between the new 16-layer discs and existing BD media.

Dampening the announcement, the 16-layer discs are read-only. That may change in time, but for the here and now, you'll still need to resort to standard discs or HDDs to store your epic  music collection, downloaded videos, and other legally acquired data. Of course, finding someone who owns a Blu-ray drive capable of burning BD discs is more rare than spoting a MacBook victory at Maximum PC.
