Inside Blue Ray Recorders

This article gives an insight on the best blu ray recorders. Blu-ray recorders store the video content on Blu-Ray discs. The corner stone for both Blu-ray and HD DVD are the same. The technology in both formats is identical, with the only difference residing in the fact that it's improved in Blu-Ray, so they can store 10 times more information. The basic principle of operation is the following - during data writing, an optical laser stores code on the disc while it spins, modifying its surface, from the centre of the disc outwards. The hollow areas are considered as '0', while the flats are '1'. Everything is binary in the world of computers so this is how this idea is implemented in the case of DVDs and Blu-ray. The laser is basically what burns those depressions on the surface of the disc, so the higher the frequency of that laser, the more 0s and 1s can be stored on the surface, hence - greater disc capacity. The name 'Blue-Ray' comes from the fact that the frequency of the that laser is so high that it reaches the blue end of the spectrum. That was the brief technological breakdown, now let's review the top blu ray recorders.
