Guilherme:
*Besides the total capacity around 25 gb or more, a blu ray disc uses the
external part for imprinting the information, think like a very smaller
filter than dvd, so you do not have problems with laser dispersion or disc
inclination that happens with dvd and makes it difficult or impossible to
read.*

I wouldn`t agree. Blu-Ray uses laser of different wavelenght (blue/violet
instead of red). Violet laser beam is thinner and can record more date on
the same surface.
