ABSTRACT:
A magnetic tape cartridge includes a cartridge case, a single tape reel, and a tape leader pin. The cartridge case has a tape leader opening in the side wall thereof. The tape reel with magnetic tape wound thereon is rotatably housed within said cartridge case. The tape leader pin is firmly attached to the leading end of said magnetic tape and is detachably held near the tape leader opening by a spring member. The surface hardness of the sliding surface of the spring member with respect to said tape leader pin is made higher than that of the tape leader pin to prevent an increase in the sliding resistance between the sliding surface of the tape leader pin and the sliding surface of a leader-pin holding spring.
