Abstract
A disk cartridge is provided for storing a recording disk in a space formed by fastening an upper half and a lower half. At least either the upper half or the lower half has a pair of groove portions defined on its right and left side surfaces from the front end to the central portion direction so as to oppose a mis-insertion preventing protrusion portion formed on a disk drive. Engagement concave portions which are engaged and held by the holding member disposed within the disk drive when the disk cartridge is loaded into the disk drive are provided on the inner surfaces of the groove portions.
