- 16 - ABSTRACT OF THE DISCLOSURE: An information disk store possesses an air circulation system in a substantially sealed housing, by means of which system, which includes a channel for directing air to the end of the hub on which the disks are mounted, and a low-pressure compartment that is shut off from the disk compartment by a main filter, a first positive pressure gradient from the bottom to the top of the housing is set up in the peripheral space adjacent to the disks. It is advantageous to also set up a second positive pressure gradient in the direction of rotation of the disks, in the peripheral space adjacent to the disks. The novel air circulation system can be used with advantage in all information disk storage systems in which the write and read operations may be adversely affected by dust and dirt.
