| 摘要 |
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. |
