Blu-ray discs today come with storage capacities of 25GB for a single-layer disc, and 50GB for a dual-layer disc. The 100GB disc adds a third storage layer for extra capacity. Media based on the BDXL format in theory will be able to offer storage capacity of up to 128GB with a fourth storage layer.
1 Icing is most effective in the immediate time period following an injury. The effect of icing diminishes significantly after about 48 hours. In an effort to reduce swelling and minimize inflammation, try to get the ice applied as soon as possible after the injury.  Apply ice directly to the injury.
To speed the healing, you should: 1  Ice your back to reduce pain and swelling as soon as you injure yourself. Do it for 20-30 minutes every 3-4 hours for 2-3 days. 2  Apply heat to your back -- but only after 2-3 days of icing it first. Use heat on your back only after the initial swelling has gone down.
