Abstract
In a recording tape cartridge, a tape-shaped leader tape which is connected to a distal end of a magnetic tape, and key members which are fixed to transverse direction end portions of the leader tape, form a leader portion. When the magnetic tape is taken-up onto a reel hub of a drive device, the leader tape is accommodated, along an entire length of the leader tape, in a slit of the reel hub, and tape holding portions of the key members are anchored at key grooves of the reel hub. An opening width of the slit at an outer peripheral surface of the reel hub is extremely small. A step, which arises at the magnetic tape which is taken-up on the reel hub, is extremely small.
