ABSTRACT:
An insert that is to be mounted on a hub of a spool positioned in a magnetic tape cartridge for permitting the spool to be attracted to the magnetic element of a computer drive mechanism includes a circular ferromagnetic disk having oppositely positioned upper and lower planar surfaces. The disk is provided with a centrally positioned through hole, and a plurality of recesses disposed radially outwardly of the centrally positioned through hole. Each recess is provided with a securing through hole for permitting the ferromagnetic disk to be secured to the spool hub of a magnetic tape cartridge. The disk can also include an annular flange that extends around the outer periphery of the disk and axially away from the upper surface, and an annular flange that surrounds the centrally positioned hole and extends axially away from the upper surface. Each of the recesses is defined by an inclined side wall that extends axially away from the upper surface of the disk and radially inwardly toward the longitudinal axis of the respective securing through hole.
