The currently commercially available blu-ray discs have the storage capacity of 25 GB. Those having two layers can store 50 GB of data. The problem in developing multiple layers disc have been to obtain a clear and stable signal from each recording layer. The frequently visited problems were crosstalk from adjacent layers and transmission loss. Pioneer managed to overcome these issues and developed a disc structure that reduces crosstalk from adjacent layers. Finally it came with a 16-layer optical disc that can play back high-quality signals from each layer.
The good news is that these high capacity discs are backward-compatible and will play on blu-ray disc players. These discs can be read using the same objective lens in current Blu-ray drives. Video game publishers and movie studios can use these discs to take more content on a single disc.
With the development of this technology, Pioneer is putting a green spin on the development. Discs with such enormous capacities mean fewer resources are consumed to deliver the same data or movies on Blu-ray media. For consumers, the main advantage of this technology is the chances of renting an entire season of a television show or collection of movies on a single disc. No need of disc-swapping.
So what do you think? Isn't it the future of data storage?
