The laser changes it focal point Alternatively you could use 2 lasers with different lenses
Caleb Ward
ever burned something using the sun and a magnifying glass? noticed that the effectiveness is greatly affected by how focused it is?

Indeed, they can't beat the responses in and in simplicity.

daily reminder 99.9% of DVD-Rs sold worldwide are cheap chinese ripoffs and not made by their brand daily reminder even in japan sony dvd-r is not great quality daily reminder that 10 years ago it was easy to find burnable dvd+r for 60 cents made by phillips or sony but today it's hard to find

I've done that before. Do you mean the layer on the top has gaps or something?
Sebastian Sullivan
The reflector layer in the middle is semi-translucent

These threads discuss technology. This automatically makes them better than 80% of the threads posted here.

imagine striped raid 0 on dual layer dvds with those dual lasers
Imagine a microscope focusing on a droplet of water .
The droplet is a little volume with some bacteriae swimming in it at different levels (in µm). To see clearly a bacteriae at one level, you have to focus on it, but you wont see any bacteriae at upper levels or lower.
The droplet : The DVD polycarbonat. The bacteriae at level 1µm : 1st layer of the DVD. Bacteriae at level 2µm : 2nd layer. Etc.

Imagine looking at a glass of water. Looking down at it you can either focus on the surface of the water or the bottom of the glass, the layer you are focusing on is crystal clear. Same with the disc, first layer is semi-translucent followed by the 2nd layer.

Intredasting.
Blu-Ray XL media have triple and even quad layer support, although more is possible. Amazing.

And? they're obsolete, no reason to have a optical drive in your PC and 4.7GB is too small to be of any use.

I use them to supply video evidence for court cases all the time.

This. Since the metal layers/dye layers are semi-transparent, the laser can "look through" them by changing the focusing point, and there's only enough energy in the point of focus to burn the dye/change the physical state of the metal alloy, all higher layers are left untouched. If you take out a lens with you and focus some light on the ants, it'll do nothing, but if you get them dead on a tiny focus point, you might kill them like that. Layers can be burnt one after another or simultaneously, if your hardware supports that, but it's kinda tricky with synchronization, so I guess it's less common.
