The Blu-ray Disc Association has formalized the BDXL and IH-BD, the first increasing the number of layers available while the second combines different types of layer.

More capacity
The BDXL is primarily intended for medical professionals or television and film, using the Blu-ray as a method of archiving and backup. Supports 128 GB (four layers) are writable only once. Only 100 GB (three layers) are rewritable. BDXL disks should also make their entry into the consumer market, a few years.

Blu-ray plays role of memory card
The Intra-Hybrid Blu-ray Disc (BD-HI) incorporates a layer BD-ROM and a layer BD-RE to have information immutable and when combined with the written data by the user. Each layer has a capacity of 25 GB. It is unfortunate that BDXL and IH-demand comics buying new scanners compatible, a simple firmware update is insufficient.
