Abstract
A tape cartridge in which tape is driven from a tape-supply hub onto a tape take-up hub by an endless drive-belt loop engaging the tape-wound hub peripheries. Tape tension variation due to the differences in the radius to the drive-belt center line and the radius to the tape center line is reduced by introducing fixed friction posts in the tape path. One post is located so as to be in constant contact with the tape as it spools off of the supply roll. Another post is located so as to be in constant contact with the tape as it winds onto the take-up roll.
