ABSTRACT:
A magnetic disk cartridge containing a floppy magnetic disk is provided with center core which has a groove where the vertical part of the core meets the flange upon which the disk is fastened by a double-sided adhesive ring. This groove can accommodate a portion of the adhesive ring which is positioned out of true. This ensures that such misalignment does not cause deformation of the disk and the deterioration in read/write performance with the disk. The groove also serves to prevent flange flashing from scraping fragments off the inside of the cartridge wall, and the possible harm such fragments cause if they stick to the disk.
