Abstract: In a recording tape cartridge, a braking member positioned at a restricting position within a reel hub in a state of abutting an inner surface of a floor plate of a case when the recording tape cartridge is not in use, is held at the restricting position by a top end surface of the braking member abutting a bottom end surface of a clutch member. Upward movement of a reel is restricted. When a release operation portion is pushed by a releasing portion of a drive device and the clutch member rotates, due to cam grooves and cam projections converting torque of the clutch member into axial direction moving force, the braking member, whose held state is cancelled by the bottom end surface sliding along the top end surface, moves to a rising-up permitting position, such that rising-up of the reel within the case is permitted.

Abstract: A metal plate of a recording tape cartridge is provided with a tapered portion at an outer circumference thereof. In a state in which the metal plate is attached at a fixed-side mold plate of a metal mold for molding a reel hub and a lower flange, a gap is formed between the tapered portion and the fixed-side mold plate. During molding, molding material flows into the gap. Because of this gap, an annular pawl portion is formed at the reel hub, which annular pawl portion integrally joins the metal plate with the reel hub by sandwiching the metal plate via the tapered portion.

Abstract: The self-centering tape reel for a single reel tape cartridge provides a magnetic tape reel that is equipped with one or more features to center the tape reel with respect to a rotatably driven feature, such as a drive chuck, in the tape drive that rotates the tape reel. The self-centering tape reel uses a chamfered ring that encircles the drive teeth formed on the tape reel that engage the drive chuck. The chamfered ring fits into a chamfer that is formed in the circumference of the spline access hole located in the bottom of the tape cartridge housing.

Abstract: The single reel tape cartridge with tape reel centering features provides one or more features to center the tape reel with respect to the interior surfaces of the tape cartridge housing and a rotatably driven feature, such as a drive chuck, in the tape drive that rotates the tape reel. The single reel tape cartridge with tape reel centering features provides mechanical positioning and centering of the tape reel with respect to the drive chuck of the tape drive when the tape cartridge is in any orientation and constrains lateral movement of the tape reel to prevent the tape reel from contacting the interior surfaces of the tape cartridge housing. This is accomplished by the use of a spring that applies a bias force to press the tape reel against the drive chuck in the tape drive, which rotates the tape reel. One end of the spring is seated in a spring sleeve that is formed in the center of the interior surface of the top section of the tape cartridge housing. The other end of the spring engages the tape reel.
