Abstract
A tape cartridge having a solid metal mount plate including a plurality of surfaces thereon simultaneously 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 the tape to a tape head in the tape drive.
