ABSTRACT:
The magnetic disk of a magnetic disk cartridge is provided with a center core assembly which comprises a main core, an upper core with grooves on one side for engagement with the ridges of a ridged, resilient ring which is provided on its non-engagement side with double-sided adhesive tape for holding the disk onto the ring. The disk attached to the ring can be held lightly but securely between the upper and main parts of the center core without the need to apply excessive clamping force.
