A disk cartridge according to the present invention includes a case body 10 , a shutter 11 and an elastic member 7 . The case body 10 has a head window 12 , which reaches a side surface, and a shutter opening groove 24 with a holding recess 26 at the bottom. The shutter portion 11 is subjected to the elastic force applied by the elastic member 7 so as to close the head window 12 , thus preventing a record/reproduce head from interfering with the case body 10 and reducing the width of the disk cartridge. Also, a gripping member, provided for a disk drive to prevent the disk cartridge from popping out due to the reactive force caused by the elastic member 7 , neither disengages itself from the holding recess 26 easily nor interferes with the head.
