Abstract
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.
