Sony, Panasonic introduce Blu-ray discs with 33.4GB layers


Panasonic and Sony have introduced the new i-MLSE (Maximum Likelihood Sequence Estimation) method this week, increasing the per-layer storage capacity of Blu-ray discs from the current 25GB to 33.4GB.

Tech-On! says the new method can use existing Blu-ray equipment, a “blue-violet laser diode with a 405 nm wavelength, and an object lens with a numeric aperture (NA) of 0.85.”

i-MLSE will be proposed to the BDA for widespread adoption, and Sony being a founding member should mean eventual adoption of the standard.
