Abstract: An integral tape path assembly (110) includes a head subassembly (112), a buffer/guide subassembly (114) and a spaced sensor/guide subassembly (116), all mounted to a common tape path plate (118). The buffer/guide subassembly includes a buffer arm (126) which pivots about an axis shared by a fixed guide (128). A Hall-effect position sensor (186) can be mechanically calibrated via an aperture (142) in a housing (132). The speed sensor/guide subassembly includes a roller (148) which serves to guide the tape on the take-up side of the tape drive system and to drive a shaft (152) holding a speed indicator (156) for a speed sensor (158). The speed sensor/guide subassembly includes a fixed-orientation washer (206) for urging the tape against an upper flange (208) of the roller. The washer is off-center sprung to counter distorting forces engendered by the tape as it engages the roller.
