Logs are storage devices where a person could store audio, graphics and text. Usually, they are used by people who wanted to record certain events or just store notes.
The logs could be activated in a user's RIG and the message was projected through the RIG's holo-displayer (Given that the user had one). The RIG would store the logs in the device's database where the user could view them at any time. However, the logs could also be transferred to a holo-displayer.
In Dead Space and Dead Space 2, audio, text and some video logs could be collected by Isaac which played immediately upon acquisition and could be played again from the database screen. Audio RIG calls made by various other characters are also added as audio logs. Upon finishing the two games, several backstory text logs are added to Isaac's inventory.
In Dead Space 3, bigger, portable holo-displayers replaced the small sized storage units as it was seen in previous games. These devices could record and play audio to it's listener. It could be assumed that the reason why these existed in the Tau Volantis colony was because the technology was not so advanced prior to the creation of the smaller storage units. However, for unknown reasons, they are present in the Lunar Colony of Earth's Moon (Possibly because they are a lot cheaper than the newer devices, given that the Lunar Colony was already a slum).
Artifacts also replaced the storage units in the third game. These artifacts could store graphics and text and also are different from each other from the outside. Artifacts resembling a Marker to a some kind of medal could be found throughout the game.
- The Dead Space 3 audio recorders appear to be using some sort of an operating system called the "Strata Messaging System". It is possible this is a futuristic equivalent to the modern-day operating system Windows.
