In second season episode Into The Labyrinth, seductive agent of the Abyss Satrina Leander convinces Harper to encode the entire All Systems University archive, a huge amount of data, onto just one of these deceptively simple coin-sized discs, intent on delivering it to her master. Too bad for her that Harper also included a sophisticated countermeasure virus designed to ensnare anyone who tries to access the contents. These discs are also seen in use by Captain Hunt and others in subsequent episodes.
