Forget BDXL's 128GB capacity, if Sony had its way, there would be 1TB Blu-ray discs in the near future.
Using a new laser that is much more powerful than current lasers, the new disc format could see capacity increased by 20 times.
The exact press release reads as follows, for those that can understand the technical stuff contained within:
A 1TB disc could yet save optical disc formats from extinction in the face of solid state storage and ever decreasing hard drive prices, although it will mean yet another upgrade to another disc format.

The exact press release reads as follows, for those that can understand the technical stuff contained within:
“This latest successful development is an all-semiconductor laser picosecond pulse source with a laser wavelength of 405 nanometers (1 nm = one-billionth of a meter) in the blue-violet region. It is capable of generating optical pulses in the ultrafast duration of 3 picoseconds (1 picosecond = one-trillionth of a second), with ultrahigh output peak power of 100 watts and repetition frequency of 1 gigahertz. Advanced control of the newly-developed and proprietarily-constructed GaN-based mode-locked semiconductor laser and semiconductor optical amplifier have enabled peak output power in excess of 100 watts to be achieved, which is more than a hundred times the world’s highest output value for conventional blue-violet pulse semiconductor lasers.â€
