At the end of last year were declared the specifications of blu-ray disks, which store video in the three-dimensional format.
Recently, the association Of blu-ray disc declared about the preparation for the announcement of two new blu-ray disk versions, which were called to increase the accessible information volume as the minimum by two times. Now the single-layer disk blu-ray allow to store 25 Gb of information, its two-layered fellow increases this volume to 50 Gb. In the plans of developers enters an increase in the quantity of blu-ray disk to three or four pieces, which will allow to store on one disk from 100 to 128 Gb. But if we allow the possibility of repeated rerecording , then maximum volume decreases to 100 Gb. This version obtained the designation BDXL - due to the associations with the large capacity (Extra large).
BDXL disks will be used, in essence, by professional users, who want large data volumes on optical disks. Gradually, BDXL will move, also, for the market of everyday devices, especially in the regions with the high propagation degree of blu-ray.
The second version is hybrid Blu-ray disk IH-BD (Intra-Hybrid blu-ray disc). It combines part with up to 25 Gb volume, and also the written part with volume to 25 Gb. Unfortunately, for the work with BDXL and IH-BD will be required new optics, but the latter can assure reverse compatibility with existing generation blu-ray disks. The first products, which correspond to BDXL and IH-BD specifications, must appear on the market in the next months.
