That's one definition of atheism. Many people here would call this "strong atheism". There don't seem to be many strong atheists around. "Weak atheism", on the other hand, is not a belief that god doesn't exist, but it means that you don't believe in any god.
For my own benefit I went to the dictionary.
Atheism:
"1. the doctrine or belief that there is no God.
2. disbelief in the existence of a supreme being or beings.
Disbelief in or denial of the existence of God or gods.
The doctrine that there is no God or gods."
Agnostic:
"One who believes that it is impossible to know whether there is a God.
One who is skeptical about the existence of God but does not profess true atheism."
Also this, which is very close to what I was saying to Starrman in another thread:
"a person who holds that the existence of the ultimate cause, as God, and the essential nature of things are unknown and unknowable, or that human knowledge is limited to experience."
This seems close to some Gnostic beliefs as I understand them.
