One of the first details that talked about the Blu-ray technology revealed from their initial moments was that this would be an extensible technology, therefore the discs would gain more storage capacity with the passage of time. These days, a standard Blu-ray can store about 50 GB, but the people of TDK’s close relationship with the format, has recently presented at land nipponese an optical disc that can store up to one terabyte of data. Blu-ray may have won the format war (or war of network marketing Tecnologico), although another war by getting the attention of consumers is being pretty tough around the globe. In some regions, its penetration is already almost total, but multiple factors required for a complete Blu-ray experience, coupled with such technology essential costs, makes that these excellent discs should still continue throwing punches in the ring. Of course, its potential as a backup system is undeniable (25 GB per disc minimum), and some films released in Blu-ray let us simply with the mouth open (recent version of Iron Man 2, for example), however, the fact that even not been conquered by full market doesn’t mean that the companies behind the Blu-ray are not preparing for what could be a future successor.

After all, the flexibility of the Blu-ray is very large, and since day one knew that the original capacity of disks could be expanded (a source of hope for those Geeks who have boxes full of cds and Dvds). This has been demonstrated recently people from TDK, Member of the Board of Directors of the Blu-ray Association, and one of the earliest advocates of that format. The presentation consists of an advanced optical disc with capacity in gross of one terabyte, exceeding twenty times what can save a Blu-ray disc on the market today. Prototypes were displayed at the CEATEC Conference which was held in Japan from 5 to 9 October. This capacity was reached to place anything less than sixteen layers of recording on a single disc, while maintaining a high light transmission and a level of error it low enough so that it can become a commercial option.

Many aspects of the Blu-ray technology have been applied and combined in this super disk, but still is a detail to be resolved, and it is the thickness of the disc. According to the official specifications of the Blu-ray, the thickness of a layer should be less than or equal to 100 micrometers, but on this new album, the number amounts to 260 micrometers, causing the optical lens aberrations. The commercial availability of the disk will depend exclusively on the level of interest showing the manufacturers, although that storage capacity could be useful not only for home users, but also for those with an intensive use of recorded material, such as the operators in a television channel. Currently, obtain a terabyte of capacity is not something impossible, but it would not be too bad having a cheap backup alternative and wide.
