No magnetic media is safe from this, but CDs and DVDs are not prone to it.
Does it also happen when a zero turns into a 1?

This is caused by a 1 going turning into a zero spontaneously or due to environmental factors like temperature entropy generation.
Good for you.
I have a PhD in Digital Music Conservation from the University of Texas at Austin.
Never happened to me, and I have (working) disks more than 10 years old.
Digital files are stored in digital filing cabinets called "directories" which are prone to "digital dust" - slight bit alterations that happen now or then.
No, I wouldn't say that, as I don't know what's your definition of "density of dust".
Now you might say that the density of dust is the same.
MP3 files do not compress much when archived as zip or rar. And what do you mean by "surface-to-volume ratio"?
That would be a naive view. Since MP3 files are smaller, they can be much more easily stacked together and held in "drawers" called archive files (Zip, Rar, Lha, etc.) ; in such a configuration, their surface-to-volume ratio is minimized.
Forgive us our ignorance.
All this is well-known in academia, alas the ignorant hordes just think that because it's bigger, it must be better.
What's "rotational velocity density"?
So over the past months there's been some discussion about the merits of lossy compression and the rotational velocity density issue.
What's an "unanchored file"?
Being an audio engineer for over 18 years, I'm going to let you in on a little secret. While rotational velocity density is indeed responsible for some deterioration of an unanchored file, there's a simple way of preventing this.
Better still, there have been some reported cases of damaged files repairing themselves, although marginally so (about 1.7 percent for the .ogg format).
I could agree with you if you could explain all those words, like "rotational velocity density" and "anchored files".
The procedure is, although effective, rather unorthodox. Rotational velocity density, as known only affects compressed files, i.e. files who's anchoring has been damaged during compression procedures.
What are those "rotational ruptures"?
Simply mounting your hard disk upside down enables centripetal forces to cancel out the rotational ruptures in the disk.
Only the ignorant hordes ignore that.
It is little known that flash memory is less reliable even than hard disks,some only lasting a year up to 18 months before failing.
What this means is digital files will suffer storage losses just like paper files suffer from decay.

How come i cant find any info on 'digital dust' anywhere on the net? Do you have any sources for the info you are presenting?

OK. But when i search for 'digital dust' there seems to be nothing.
So, what happens to these massive blocks of data? Well the majority of it sits on servers, collecting digital dust. Even after the data is run through analytical software that groups commonalities and segments it into useful information, most of the data goes to waste. Is there a way companies can reduce “data waste”?
Digital Dust , digital dust meaning , definition of digital dust , what is digital dust - When you download a song on your ipod or computer and listen to it for like a week and never again, but leave it on there anyway.
Some examples : I really used to like Three Days Grace, but now all their songs are just collecting digital dust on my ipod.
