A Troubling Question

Is there a difference in mass between a DVD containing 1MB of data, and
the exact same DVD containing 6GB of data?

It can't be...

If the laser were to remove/add mass, then a re-writable DVD couldn't
reverse this process.

It is, indeed, thoroughly perplexing.

It's not at all perplexing. A CD/DVD is the same weight whether it's full of
data or empty.

What ever made you think it might be heavier.

Perhaps a mirror is lighter when it's dark?

1) probably not. not unless those little laser diodes are a whole lot more
powerful than i thought.

2) 6GB weighs a lot more. in fact im surprised you can carry them at all.
if you can, its because you are one of those rare people who resonates at
the same frequency as the leptons in the dvd plastic. please be careful
around genetically engineered watermelons.

Exactly the same, I would say.... given that the recorder and player neither
add or remove anything physical, so there should be no change in mass.

 

Thanks. I'd been looking for a particularly stupid Usenet discussion as
part of a pet project, and this has to be it.

Congratulations on the stupidest contribution thereto.

You've taken a snippet of theory and mis-used it.

The information on a DVD is constant. The laser simply changes it around
from something we call empty, to something we call full.

(and will everyone stop crossposting this thread?)

Pathetic. I don't see your intellectual contribution to the debate.

What crosspost? The only thing I've seen is your response to this
amazingly obvious bait. I'd check your filters.

Crossposts restored so other people can consider your reply.

So what? I'm trying to get as many people to answer as possible. It is not
an easy question to answer and, as you can see, there are many
disagreements.

Cite your sources!

i think 0s weigh more than 1s. more surface area.

This is almost as amusing as the bloke who wanted to know how much
heavier his charged batteries were than when discharged..

I think we came out at 10^-19 grams or something...
In the case of a DVD. obviously its lighter if it has more holes burnt
in it..;=)
