In a bit of technology, the Red Laser-based DVDs use the Blu-ray disc format using Blue Laser technology. This technology allows video compression with complex processing algorithms to be able to playback high-definition video on the same size disc as a standard DVD disc.

The advantage of Blue-laser technology is that it is narrower than Red-laser, which means that information can be more accurately focused on the disk surface. Taking advantage of this, engineers were able to create “black holes” on the disk, where information was stored smaller. And every such “black hole” will increase the amount of storage on the disk, which is useful for high-definition video recording.
