ABSTRACT:
A disk cartridge having a housing in which a substantially rigid disk is completely enclosed, the disk having a nub which is accessible through an opening in the housing for engagement by a rotatable drive spindle. The housing has an opening for receiving a read/write head to apply or pick off data from the magnetically permeable surface of the disk. The head receiving opening is normally closed by a door which is opened by a cam when the cartridge is inserted in a drive unit. When not in use, the disk hub is held against the interior of the hub opening to seal the cartridge against contamination. When the cartridge is inserted in a drive unit, the drive spindle is guided into a self-centering socket in the hub and lifts the hub clear of the opening for free rotation of the disk.
