Abstract
A rotating disk storage device has a plurality of disks fitted onto a spindle, transducers supported by transducer supporting means for movement in face-to-face relationship with surfaces of the disks, and drive means for causing the transducer supporting means to move in a predetermined direction. Separating means provides for separation of a disk housing for housing the disks and a drive-mechanism housing for housing a drive mechanism. The separating means has a first opening for allowing the discharge of gas for cooling the drive mechanism and a second opening for allowing the gas which has cooled it to be discharged via discharge means. The separating means has flow resisting means on the side of the disk housing so as to prevent the gas from flowing backward into the first and second openings.
