Quadruple-layer Blu-ray Disc stores massive 128 GB of data

Posted by Mike Luttrell

One single Blu-ray Disc can now store more than 27 times the capacity of a standard DVD, as the Blu-ray Disc Association has approved a quad-layer "BDXL" standard.

The BDXL standard also provides specification for a triple-layer re-writable Blu-ray Disc capacity of 100 GB. However, DigitalTrends.com reports that no Blu-ray player on the market today will be compatible with BDXL.
The format is preliminarily being targeted at professional applications such as archiving and medial imaging. However, years down the line, especially as more data-intensive 3D Blu-ray content becomes pervasive, expect BDXL to come to the home market as well.

The announcement is big news for the Blu-ray Disc Association, as it shows that technology is still improving and evolving for the world of disc-based media.

"The BDA worked diligently to create an extension of the Blu-ray Disc format that leverages the physical structure of the design of the disc to create even more storage capacity," said the association's committee chair Victor Matsuda in a statement.
