Sony and Panasonic have unveiled research that could lead to 67 GB Blu-ray discs, 33.4 GB on each layer (up from 25 GB), and these new disc would not need new lasers to be read or burned.
Based on a new evaluation technique called i-MLSE (Maximum Likelihood Sequence Estimation), the changes are mainly in software and would increase the ability of drives to judge the optical quality. Increased processing is needed for drives to read and write to media, and as such some drives that have slower processors may not have the power needed, but assuming processing power is there, no new hardware will be required.
