Magnetoresistive (MR) sensors are disclosed that have leads with reduced
resistance, improving the signal-to-noise ratio of the sensors. The leads
have broad layers of highly conductive material for connection to MR
structures, as opposed to thin wires of highly conductive material or
broad layers of resistive material, lowering the resistance of the leads.
The low-resistance leads can be formed without increasing the
shield-to-shield spacing, providing highly sensitive and focused MR
sensors.
