Abstract
Abstract A reel-over-reel tape cartridge having a pair of axially aligned tape hubs and improved means for mounting the hubs for rotation independently of each other within a cartridge housing. One hub has a tubular extension permitting it to be rotatably mounted on one wall member of the housing and the other hub has an extension and a tubular body to permit it to be rotatably mounted on the one hub and on a second wall member of the cartridge housing. The hubs are formed to permit a rotatable drive member to be alternately coupled thereto to cause rotation thereof in the same direction to avoid the need for a reversible drive means for the hubs. The cartridge can be provided with a removable reel having a tape which mates with a tape leader attached to a rotatable hub in the cartridge for receiving the tape of the removable reel. The removable reel feature can also be used with a cartridge having the reels side by side with each other.
