A system includes a library compartment, a player and a gas generator. The library compartment houses a plurality of data storage disks. The player is external to the library compartment and comprises a head that is configured to interact with at least one of the plurality of data storage disks. The gas generator is fluidly connected to the player. An embodiment includes a partition between the library compartment and player, the partition including a selectively openable interlock. In an embodiment, the player has a negative fluid pressure relative to the library compartment. A method of controlling an environment in a disk player is also described. The method includes detecting a composition of a fluid environment in the disk player and detecting a pressure of the fluid environment in the disk player.
