Size does matter, and so does density.

Bingo.

And welcome to the boards ljdarten, hope you decide to stick around and set some other discussions straight.

Density doesn't necessarily add to the physical dimensions of an object. Two DVD's side by side can have the same depth, width and height. But one of them can be denser and hold more data (eg. Blu-ray disc). Of course, there are times when you can hit a cap, but with science you usually can get past it if the technology is there.

I shall once again quote ljdarten

every part is necessary. Yes, density will make a disc have less space, but so will size.

Blu-ray discs can hold more info than a DVD, despite their size, because of... well I'll let the Blu-ray people explain:

The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB. Recent development by Pioneer has pushed the storage capacity to 500GB on a single disc by using 20 layers.

Of course, two blu-ray discs of equal layers but unequal size would result in the larger being able to store more data, simply because of its size.

Or as Nick the Punk said:

Wurd.

I find the resident evil ps2 controlls are better.
