Abstract: An apparatus according to one embodiment includes a transducer structure having a lower shield and an upper shield above the lower shield, the upper and lower shields providing magnetic shielding. A current-perpendicular-to-plane sensor is positioned between the upper and lower shields. An electrical lead layer is positioned between the sensor and one of the shields. The electrical lead layer is in electrical communication with the sensor. A spacer layer is positioned between the electrical lead layer and the one of the shields. A conductivity of the electrical lead layer is higher than a conductivity of the spacer layer.

Abstract: A thin film inductor with top and bottom pole pieces that are mechanically connected to each other at at least two via zones, to create a magnetically permeable yoke that defines at least one interior space. Enclosed portion(s) of a winding member pass through the interior space(s) of the yoke. The enclosed portion(s) of the winding member define an axial direction and a transverse direction. The pole pieces extend beyond the via zones in the axial and/or transverse direction. The extended pole pieces improve magnetic performance of the thin film inductor, by effectively moving pole piece edges away from locations of high magnetic flux density.

Abstract: An apparatus according to one embodiment includes a transducer structure having: a lower shield having recesses in an upper surface thereof; an upper shield formed above the lower shield; a sensor between the upper and lower shields, the recesses being positioned on opposite sides of the sensor; and a first insulating layer in the recesses in the upper surface of the lower shield. An upper surface of the first insulating layer is coplanar with an uppermost portion of the upper surface of the lower shield. An apparatus according to another embodiment includes a transducer structure having: a lower shield having recesses in an upper surface thereof; an upper shield formed above the lower shield, the upper shield having recesses in a lower surface thereof; a sensor between the shields, the recesses being positioned on opposite sides of the sensor; and insulating layers in the recesses in the shields.

Abstract: A tape write transducer includes a first yoke member, a second yoke member and a shield member arranged in a row so that row includes two gaps: an inter-yoke-member gap (between the two yoke members), and a shield-member gap (between one of the yoke members and the shield member). In operations using an underlayerless tape, the magnetic field in the inter-yoke member gap causes magnetic transitions to be written to the underlayerless recording medium in a point along the tape that is in vicinity to the inter-yoke-member gap. In operations using an underlayer tape, the magnetic field in the shield-member gap causes magnetic transitions to be written to the underlayer tape recording layer at a point along the tape that is in vicinity to the shield-member gap.

The at least one lead is in electrical communication with the sensor. A width of one or more of the at least one lead in a cross track direction is about equal to a width of the sensor.
