Disc or Disk?

Just thought I'd put up a quick post of some goings on with the fork. And in case you're wondering, it seems that it's both disc and disk. Depending on what company, what component, and sometimes even within the same description, it's spelled both ways. As someone who has a hard enough time spelling as it is, things like this don't help.
