Abstract
A memory storage disk module comprising a memory storage disk unit including at least one memory storage disk, and at least one head able to access the disk for writing and reading data to and from the disk, and a control circuit board. A cover is provided to cover the memory storage disk unit and the control circuit board, and the cover constitutes a shield against an emission of electromagnetic waves, as well as a duct for a flow of cooling air. The cover is composed of a substantially solid main panel portion and front and rear panel portions having small apertures, respectively, allowing air to flow therethrough. A memory storage disk system comprises a plurality of memory storage disk modules, and a rack having the memory storage disk modules therein releasably mounted and being substantially unaffected by electromagnetic waves.
