ABSTRACT:
An interchangeable random-access magnetic storage element, comprising an electromagnetic disk disposed in a substantially cylindrical dust-proof enclosure, which as an assembly can be fitted onto a drive spindle of a drive means. The enclosure comprises two covers which are clamped against each other with the insertion of dust seals, which together with the magnetic disk are rotated by the drive spindle, the upper cover being axially lifted by lifting cams provided on the drive spindle, so that an annular slot is obtained between the lower and upper cover for the passage of electromagnetic recording and reproducing means. At its top the drive spindle comprises an axially movable pressure member, which upon closure of a cover of the drive means is depressed and thus clamps the electromagnetic disk onto the spindle and simultaneously lifts the upper cover.
