    • 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.
    • 信息盘存储器具有基本上密封的壳体中的空气循环系统,通过该系统包括用于将空气引导到其上安装有盘的轮毂的端部的通道和关闭的低压隔室 通过主过滤器从盘盒隔离,在与盘相邻的周边空间中建立从壳体的底部到顶部的第一正压梯度。 有利的是,在与盘相邻的外围空间中,在盘的旋转方向上设置第二正压梯度。 在所有信息盘存储系统中,新颖的空气循环系统可以被有利地用于写入和读取操作可能受到灰尘和污垢的不利影响。
