A magnetic head suspension design which eliminates the need for the customary arms in magnetic recording files is disclosed. This design is applicable for magnetic recording disk files with one head per recording surface, which is now standard for 5 1/4" diameter or smaller disks. By combining the arm and two head suspensions into a single piece, costly suspension to arm connections are eliminated. In addition, the dynamic performance (e.g., resonant frequencies and actuator access time) is greatly enhanced due to the reduction in moving mass. As shown in the figure, the length of regular head suspensions are increased to include the length of the arm. Two suspensions, one for the up-facing head and one for the down-facing head, are formed in the conventional way.
