Abstract
A belt-driven tape cartridge having more internal tape storage capacity than prior art cartridges adhering to a standard, but having the same outside dimensions as such a standard cartridge. The invention optimizes internal tape storage capacity in a approximately standard quarter inch cartridge by optimizing the geometric configuration and placement of internal tape guide rollers, repositioning internal side walls, and optimizing the size of the tape drive roller. Compared to the standard, the tape guide rollers are reduced in diameter and moved further away from the center line of the tape reels. Also in comparison to the standard, the side walls are also repositioned further away from the radial center of the tape reels. Optionally, the drive interface portion of the belt drive roller is decreased in size, while the required linear velocity of the tape is maintained by proportionally decreasing the radius of the belt interface portion of the belt drive roller.
