Abstract
A hermetically sealed, helium filled magnetic disk storage file is disclosed in which a thin walled container encloses the disk file. The container body is clamped between the baseplate of the file and an external mounting bracket which mounts the file to a frame so that the container "floats" relative to both the frame and the baseplate. A double-seamed visco-elastic seal is employed for attaching the cover of the container to the container body.
