Head positioning mechanism for multi-track tape recorders

摘要

A mechanism 62 for precisely positioning the recording / reproducing head 30 on the central portion of the track including the stepper motor 52 and the coil assembly 60 for controlling coarse and precise crosshead positioning of the coils 62 To the pivoting actuator arm 32 which provides the mounting member 30 for the recording / reproducing head. A torsion spring 46 is attached to the end 44 and the actuator arm 32 driven by the stepper motor lead screw 36 to incrementally position the actuator arm. The coiled food (60) includes a coil bundle (62) that lies side by side between two or more sets of split magnets (40). The coil assembly operates to provide fine positioning control by alternately turning the write / read head.
