Some time before, spread the news concerning the emergence of Blue Ray Disc (BRD) that it seems will replace the CD function and DVD. If CD could keep the data as far as 600-700 clouds Byte (MB), and DVD only 17.5 Gega Byte (GB), then the BRD capacity far more horrifying, 50 GB!
In accordance with his name, this technology used the blue laser in a long manner the wave 405 nanometer (nm). This was different from CD and DVD that used the red laser, in a long manner the wave 780nm (CD) or 635-650 nm (DVD).

Blue Ray used 1-2 layers in each one of his slivers, where every player could accommodate the data totalling 25 GB. DVD also had two layers, but his capacity of only 17.5 of GB. Whereas CD only had one layer had a capacity of 650-700 of MB. Not only, the speed of BRD access in recording the data was also far more faster, that is 36 MB per the second (mbbs). Compared with DVD that only 11 mbbs, moreover CD that only 1.2 mbbs. At this time technology of Blue Ray already implementationed to Sony Playstation 3, was good for the use in personal computer (PC), the disc, and player him. FM Disc Apart from Blue Ray, we also had the alternative as the storage media of the data. One of them was Fluorescent Multi-Layer of Disc (FM Disc). This technology was initially developed by Constellation 3D, the company that had headquarters in the US, but had the laboratory in Israel and Russia. FM Disc was results of the development of the discovery of the organic matter that was mentioned stable photochrome. This material if being affected by the laser beam could radiate the light fluoroscent. If the CD surface and DVD were scratched, then the data will be difficult to be read. Was different from FM Disc, where the data continued to be able to be read although his surface was scratched or dirty. Why could like that? Because the characteristics of the light to FM Disc were incoherent. It is another matter with CD and DVD that were coherent. From the aspect of the form, FM Disc had the form a measurement with CD,DVD, and BSD, but transparent, was not gotten by the layer Shone like the generation beforehand. FM Disc had more layers, that is for the capacity 50 GB was needed by 12 layers with the speed of very extraordinary access. The BRD presence and FM Disc clearly all of a sudden did not drag long technology as CD and DVD. cause needed the process for quite a long time. However, at least we have had many choices about the storage media of the data. (Sriyati)
