ABSTRACT:
A magnetic disk memory device of the invention has a shroud accommodating replaceable or changeable disk packs and air passages through which air is circulated to cool the disk packs and the access mechanism. This air passage is formed, when a shroud cover for closing the space in the shroud is in the closing position, to recirculate the air through the space in the shroud, while, when the shroud cover is in the opening position, to discharge the air delivered by a blower to the outside of the shroud through the opening of the latter. The air passage has an air filter for filtrating the air.
