    摘要： In an example, a method comprises aligning a central axis (212a) of a paddle portion (212) on a write pole circuit to be substantially perpendicular to an adjacent magnetic surface, and bending a central axis (214a) of an extended tip portion (214) relative to the central axis of the paddle portion. In another example, a transducer head comprises a write pole circuit having a paddle portion (212) with a central axis (212a), and an extended tip portion (214) with a central axis (214a), the central axis of the extended tip portion angled from the central axis of the paddle portion. In another example, a magnetic circuit comprises a write pole circuit having a paddle portion (212) and an extended tip portion (214), the extended tip portion bending away from a central axis of the paddle portion, and a coil (250) wrapping around the extended tip portion.

    摘要： A near field transducer antenna has a first end proximate a media writing surface and a second end proximate a waveguide that delivers light to the antenna. The antenna includes an aperture disposed along a propagation axis that extends from the first end to the second end. A notch protrudes within the aperture. The notch is facing an opening of the aperture that extends along the propagation axis. A magnetic pole is proximate the antenna, and includes a first portion of magnetic material and a second portion of antenna material. The second portion is disposed over the opening of the aperture and facing the notch of the antenna.

    摘要： A method of detecting a contact between a transducing head and a storage medium is provided. The method applies an input signal, having a select power level and known frequency, to an actuator for actuating the head. An output signal is obtained in response to the input signal. At least one signal component is extracted from the output signal at the same or a harmonic of the same known frequency as the input signal applied to the actuator. Whether the at least one extracted signal component indicates a contact between the head and the medium is determined. The power level of the applied wave pattern is increased incrementally until the extracted signal component indicates a contact between the head and the storage medium.

    摘要： A sensor supported by a head transducer has a temperature coefficient of resistance (TCR) and a sensor resistance. The sensor operates at a temperature above ambient and is responsive to changes in sensor-medium spacing. Conductive contacts connected to the sensor have a contact resistance and a cross-sectional area adjacent to the sensor larger than that of the sensor, such that the contact resistance is small relative to the sensor resistance and negligibly contributes to a signal generated by the sensor. A multiplicity of head transducers each support a TCR sensor and a power source can supply bias power to each sensor of each head to maintain each sensor at a fixed temperature above an ambient temperature in the presence of heat transfer changes impacting the sensors. A TCR sensor of a head transducer can include a track-oriented TCR sensor wire for sensing one or both of asperities of the medium.
