Blu-ray is Going 33.4 GB

This issue may not be a concern at present but any benefit it would offer is a welcome development.  The Blu-ray disc looks set for a boost from its present 25 GB per layer capacity to 33.4 GB per layer.  Sony and Panasonic are busily working together on a new method to increase the capacity by employing a new Blu-ray media evaluation scheme called the Maximum Likelihood Sequence Estimation evaluation index or i-MLSE.  This is a new method of estimating read error rate of discs and will still use the current Blu-ray optics.  i-MSE is a complex process but recent advancements in hardware has made possible for it to be used in real time in Blu-ray discs.  This development was announced at the International Symposium on Optical Memory (ISOM) 2009 held last October 2009.  There was no timeline yet for the  rollout but as per industry sources, Sony will lobby to the Blu-ray Disc Association, of which it is the leading member, the widespread adoption of i-MLSE.
