Optical discs slowly but surely go out of circulation. First of all, because of the high-speed Internet access and the lack of wearable information on optical discs. The second drawback is designed to fight the new optical BD disks from Sony.
New BD-R XL — have the ability to four-layer recording, which allows to save the information on the disk up to 128 gigabytes. The new disks are perfect for storing user information, as well as for distributing licensed software, which for some reason does not spread through the network.
The estimated cost of one disc – $ 13, a packaging of 5 discs – $ 53.
