摘要： A recording tape cartridge capable of keeping position error signals during running of a recording tape small. A recording tape cartridge is provided with a reel hub, a magnetic tape that is wound round the reel hub, and a lower flange and upper flange that are disposed to oppose one another at each of the both axial direction ends of the reel hub. In a state in which the magnetic tape is completely wound on the reel hub, the magnetic tape is offset toward the upper flange. A space of an edge clearance between a lower end of an outermost periphery portion of the magnetic tape and the lower flange is at least 0.18 mm and at most 0.46 mm. A rate of widening of a facing distance between the lower flange and the upper flange increases toward the outer periphery side.

摘要： A recording tape cartridge can prevent release of rotation locking of a reel with respect to a case accompanying dropping of the recording tape cartridge. The tape recording cartridge is configured to rotatably accommodate within a case a reel that has magnetic tape wound on a reel hub. Within the reel hub, external teeth of a brake gear, of a brake member that is supported so as to be non-rotatable with respect to the case, mesh with an engaged gear having internal teeth, preventing rotation of the reel with respect to the case. Lock portions of lock members are inserted between the reel positioned biased to a bottom panel side by a compression coil spring, and a top panel, thereby preventing movement of the reel with respect to the case in the reel axial direction.

摘要： A recording tape cartridge includes a leader member that is attached to an end portion of recording tape and on both ends of which flange portions are formed, and holding portions that are formed in an upper case and a lower case and hold the leader member in the vicinity of an opening. Projecting portions are formed on the holding portions and overlap the flange portions on inner surface sides of the flange portions. Through holes are formed in the upper case and the lower case, whereby undercut portions are not present in the projecting portions. The case of the recording tape cartridge can be molded without complicating the configuration of the mold.
