Abstract: A method may comprise relaying a wireless signal via a bi-directional, full-duplex relay. The relay may comprise an analog uplink relay and an analog downlink relay, and may relay signals between a transmitter and a backscatter node. The spectrum of the downlink signal transmitted by the downlink relay may be different than the spectrum of the uplink signal received by the uplink relay. Filtering may attenuate leakage from the downlink relay to the uplink relay, and vice versa. The uplink relay may create a phase offset that is opposite in sign and substantially equal in magnitude to the phase offset created by the downlink relay. The downlink and uplink relays, taken together, may create a substantially constant net phase offset. The full-duplex relay may be housed in a vehicle that moves, and may be used to determine spatial coordinates of backscatter sources that are located in the relay's environment.

The LS2 layer has a notch filled with dielectric material at the air bearing surface (ABS) that extends to a height?h1, or may be completely replaced with dielectric material. Two notch front sides each form an angle ? with the LS1 bottom surface, and two notch inner sides between the ABS and LS2 backside form angle ? with the ABS where each of ? and ? is from 10 degrees to 170 degrees. Accordingly, bits per square inch performance is improved while substantially maintaining tracks per square inch capability for an overall gain in area density capability.

A write current passes from a BC outer portion below the main pole in the selected writer through the BC center portion to the interconnect, and then through the DC center portion to a DC outer portion above the main pole in the selected writer. Area density capability mean and sigma are improved.
