Magnetic read head having a CPP MR sensor electrically isolated from a top shield

摘要

An apparatus having a transducer structure with: a lower shield; an upper shield above the lower shield, the shields providing magnetic shielding; a current-perpendicular-to-plane sensor between the upper and lower shields; at least one of an upper electrical lead between the sensor and the upper shield and a lower electrical lead between the sensor and the lower shield, the at least one lead being in electrical communication with the sensor; and an insulating layer between the at least one of the leads and the shield closest thereto. Another embodiment includes a transducer structure having: a lower shield; an upper shield above the lower shield; a current-perpendicular-to-plane sensor between the upper and lower shields; an upper electrical lead between the sensor and the upper shield, the upper electrical lead being in electrical communication with the sensor; and an insulating layer between at upper electrical lead and the upper shield.

1. An apparatus, comprising:
an array of reader transducer structures on a first module, each reader transducer structure in the array having:
a lower shield;an upper shield above the lower shield, the shields providing magnetic shielding;a current-perpendicular-to-plane sensor between the upper and lower shields;at least one of an upper electrical lead between the sensor and the upper shield and a lower electrical lead between the sensor and the lower shield, the at least one of the leads being in electrical communication with the sensor; andan insulating layer between the at least one of the leads and the shield closest thereto,wherein a width of the at least one of the leads in a cross track direction is less than a width of the shield closest thereto, wherein the width of the at least one of the leads in the cross track direction is greater than a width of the sensor; and an array of writer transducer structures on a second module spaced from the first module and arranged to enable read-while-write capability on a magnetic recording tape.
