A file protect actuator for a cartridge can include a rectangular column mounted between two disk-like supports with the column offset from the center of rotation of the disks. The assembly is mounted for rotation within the cartridge at an edge such that a switch probe can enter an opening in the cartridge to determine the rotational position of the actuator as determined by the position of the column in relationship to the edge of the cartridge. As shown in Fig. 1, the actuator includes a rectangular column 1 mounted between two circular disk-like supports, top support 2 and bottom support 3. View A-A taken along line A-A of Fig. 1 shows the rectangular shape of the actuator 1 and its offset position relative to the center of rotation of support 3. Fig. 2 is a top view of the file protect device of Fig. 1.
