Abstract: A tape cartridge (10) having a solid metal mount plate (12) including a plurality of surfaces (51, 52, 53) thereon simultaneously machined to the same plane. Tape reels (200, 300) and tape guides (105, 125) are affixed to the mount plate (12), thereby ensuring precise alignment to each other. A portion of at least one of the surfaces is exposed to the outside of the tape cartridge (10) by recesses (30, 31) in the tape cartridge cover. Upon seating the tape cartridge (10) in a tape drive, guides (105, 125) are inserted into the recesses, thereby ensuring precise alignment of tape wound upon the tape to a tape head in the tape drive.

Abstract: A tape reel brake (207) which is mounted in a well (215) in the top of a tape reel hub. The brake (207) is mounted to be compliantly biased away from the base of the well (215). The hub and brake (207) are seated in the tape cartridge (10) such that teeth (239) on the periphery of the brake (207) are biased against the opposite inside surface (14) of the cartridge housing about the periphery of an opening (20) therein. The biasing of the brake (207) against the opposite inside surface (14) both prevents the rotation of the reel (200) and shields out dust when the tape cartridge (10) is removed from a tape drive. To rotate the reel (200), a tape drive clutch enters the opening (20) in the opposite inside surface and depresses the brake (207) into the well (215) to mate with a smaller diameter portion (220) of the hub.
