Meet the Super DVD: Scientists Develop Massive 1 Petabit Optical Disk (gizmodo.com)

Note: Unfortunately the research paper linked in the article is a dead/broken/wrong link. Perhaps the author will update it later.

From the limited coverage, it doesn't sound like there's an actual optical drive that utilizes this yet and that it's just theoretical based on the properties of the material the researchers developed.

I'm not holding my breath, but I would absolutely love to be able to back up my storage system to a single optical disc (even if tens of TBs go unused).

If they could make a R/W version of that, holy crap.

A byte in this context always means 8 bit though, it has nothing to do with powers of 10 or 2. The prefix of K (kilo), M (mega), G (giga) or Ki (kibi), Mi (mebi), Gi (gibi) doesn't change the meaning of "byte".

Yes this is right. There may be confusion happening with binary and metric prefixes.

For example:

Kibbibyte (1024 bytes) vs Kilobyte (1000 bytes).
