Abstract: A tape transport fits within the five and one-quarter inch form factor and has motor driven mechanisms for automatically loading a DC600-type cartridge endwise therein. The transport includes a frame dimensioned to fit within the form factor, and a front panel extending across a forward transvere end of the frame. The front panel has a slot dimensioned so that the cartridge can be endwise inserted through the slot onto a tray movably supported within the frame. A read/write head is mounted to the frame adjacent the tray for reciprocating the head along an axis perpendicular to a base plate of the cartridge. A capstan drive motor is also mounted to the frame adjacent the tray so that a capstan drive roller connected to its shaft can drive a belt capstan roller of the cartridge. Guides associated with the tray permit the same to be moved by a motor driven gear box to automatically carry the cartridge rearwardly and then laterally into engagement with the read/write head and the capstan drive roller.
