Abstract: The present invention provides machine and human readable information for a data cartridge (10) other item to be stored. In one embodiment, a label, on which human readable information is printed or similarly marked, is applied to cover an indicator area (28) of the cartridge. The indicator area of the cartridge has recesses (18) formed therein; corresponding positions on the indicator area of the label overlay the recesses and can be either open or closed. An open position allows a mechanical, spring-loaded finger (34) on a data drive to engage the exposed recess and activate or deactivate a connected switch. Information, matching the printed human readable information, can thus be encoded in the label and machine read by the data drive.

Abstract: The invention is a tape cartridge having a solid metal mount plate including a plurality of surfaces thereon simultaenously machined to the same plane. Tape reels and tape guides are affixed to the mount plate, 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 by recesses in the tape cartridge cover. Upon seating the tape cartridge in a tape drive, guides are inserted into the recesses, thereby ensuring precise alignment of tape wound upon the tape to a tape head in the tape drive.

Abstract: The invention is a tape reel brake which is mounted in a well in the top of a tape reel hub. The well is inside the tape bearing surface of the hub. The brake is mounted to be compliantly biased away from the base of the well. The hub is seated against a first inside surface of a tape cartridge housing. The hub and brake are seated in the tape cartridge such that teeth on the periphery of the brake are biased against the opposite inside surface of the cartridge housing about the periphery of an opening therein. The biasing of the brake against the opposite inside surface both prevents the rotation of the reel and shields out dust when the tape cartridge is removed from a tape drive. To rotate the reel, a tape drive clutch enters the opening in the opposite inside surface and depresses the brake into the well to mate with a smaller diameter portion of the hub or a recessed portion of the brake. The hub is always maintained on the inside surface of the housing, thereby eliminating lateral motion which could disrupt the tape path.
