M4 Field Disks (also known as Recorder Chips or Helmet Chips) are used in Helmet Recorders to store visual and audio files created by the recorder's video and sound sensors. They can be plugged into nearly any information terminal or display unit that can play optical and audio data.
During the Battle of Sigma Octanus IV, the Spartan-IIs employed these, and SPARTAN-117's Recorder chip contained the record of his mission to Côte d'Azur, as well as intelligence on Covenant Huragoks and Lekgolos. This was much appreciated by HIGHCOM.
Private Jenkins' helmet was equipped with one, and SPARTAN-117 used a playback system in his helmet to view the squad's progress as he tried to find Captain Keyes. It was using this chip's recording that he first saw the Flood[1].
Trivia
- The chips have the words "DO NOT EAT" printed on them. This is most likely a reference to them sharing the same name as potato chips.
- These chips seem to fit inside the Spartan helmet, similar to how an AI's chip would fit inside, although it does not feel the same.
