A dual layer flexible circuit for tape drives is provided that has a
flexible substrate with first and second sides. A plurality of write
trace pairs are provided on the substrate, with each write trace pair
including a first write trace on the first side of the substrate and a
second write trace on the second side of the substrate opposing the first
write trace. Each first write trace has a width that is narrower than the
width of each second write trace, thereby allowing for compensation of
misalignment between the trace layers, avoiding variation in the
capacitance and inductance of the full circuit.
