A MAGNETIC TAPE DRIVE FOR READING/WRITING DATA ON MAGNETIC TAPE IN A CARTRIDGE OF THE TYPE IN WHICH A DRIVEN ROLLER IN THE CARTRIDGE MOVES TAPE PAST A READ/ WRITE HEAD IN THE DRIVE, HAS A DOOR OPENING LEVER DISPOSED PARALLEL TO THE DIRECTION OF INSERTION OF THE CARTRIDGE. THE LEVER IS MOUNTED ON A PIVOT AT ONE END ON AN AXIS PERPENDICULAR TO THE DIRECTION OF INSERTION OF THE CARTRIDGE. THE OUTER END OF THE LEVER BEARS AGAINST THE ACTUATING PORTION OF THE DOOR TO OPEN THE DOOR AS THE CARTRIDGE ENTERS THE DRIVE. THE LEVER IS MOVEABLE ABOUT ITS PIVOT ONLY TO THE SIDE OF THE CARTRIDGE TO ACCOMODATE AN INSERTION OF THE CARTRIDGE INTO THE DRIVE.
