Animus data fragments were fragments that were collected during Desmond Miles Animus sessions. Collecting one of them would open up a small memory for him, which he could play while he was on Animus Island.

Trivia There is also an Achievement for collecting all Animus data fragments, called "Capped" (20G; Silver Trophy). The Animus data fragments looks like the loading bar in Assassin's Creed II.
