A fire-resistant container for protecting magnetic media such as floppy discs comprises a base and a cover. The base is in the form of an outer casing and an inner container separated by thermal insulation material which is maintained under compressive stress so as to retain the inner container in position within the outer casing and to permit the insulation material to expand when the outer casing expands as a result of exposure to high temperature. The inner container may have a hollow wall which is filled with wax. The cover may comprise a dished outer cover, an inner cover and thermal insulation material which is maintained under compressive stress.

A container for protecting magnetic media from fire, which container comprises a base and a cover, the base comprising an outer casing of fire and impact resistant material and an inner container defining a storage cavity for the magnetic media, the outer casing and the inner container being separated by thermal insulation material, wherein the thermal insulation material is maintained under compressive stress so as to provide the sole support for the inner container and to maintain the inner container firmly in position within the outer casing and to expand when the outer casing expands as a result of exposure to higher temperature, said thermal insulation material comprising a microporous material compacted to a density above 150 kg/m3.
