Triple-layer Blu-ray discs for 4K video teased with 100GB capacity

Blu-ray disc producer outs format before official announcement

Blu-ray discs for 4K content are already being made, with one disc producer claiming to be testing the production of the 100GB-capacity media. Singulus has revealed it has created its new replication line for triple-layer Blu-ray discs, ahead of an expected announcement of the technology from the Blu-ray Disc Association.

The confirmation, in the form of a press release spotted by TechRadar, states that the 100GB figure comes from not only using three layers rather than two or one, but also that a change in the data compression method allows for up to 33GB of information to be stored on each layer, instead of the current 25GB.

The BDA has yet to formally announce an enhanced Blu-ray format, but a spokesperson speaking to TechRadar hopes that it can be revealed before the end of this year. It is keen to avoid another format war, such as that between Blu-Ray and HD-DVD, though it is quick to point out that competing systems, such as the joint effort by Sony and Panasonic on 300GB optical disc storage, are more for enterprise, with the final version heading to consumers consisting of a single optical disc.

A new high-density media format is likely to help the adoption of Ultra HD televisions, due to current media distribution issues. Testing by Netflix and Sony's launched 4K download service will be hampered by those using low-bandwidth connections, while 4K-resolution television broadcasts are still only in testing.
