Stripe height lapping control structures for a multiple sensor array
A method and system provide a storage device. A plurality of read sensor stacks for each reader of the storage device are provided. The read sensor stacks are distributed along a down track direction and offset in a cross-track direction. A plurality of electronic lapping guides (ELGs) are provided for the read sensor stacks. The read sensor stacks are lapped. Lapping is terminated based on signal(s) from the ELG(s).
1. A magnetic read transducer comprising:
a first read sensor;
a second read sensor;
a third read sensor;
a first electronic lapping guide associated with the first read sensor to control a stripe height of the first read sensor;
a second electronic lapping guide associated with the second read sensor to control the stripe height of the second read sensor; and
a third electronic lapping guide associated with the third read sensor to control the stripe height of the third read sensor,
wherein the first electronic lapping guide is connected to a common ground connector, and wherein the third electronic lapping guide is connected to a common pad.
2. The magnetic read transducer of claim 1 , wherein the first read sensor and the second read sensor are separated by a first distance, wherein the first electronic lapping guide and the second electronic lapping guide are separated by a second distance, and wherein the first distance is substantially same as the second distance.
3. The magnetic read transducer of claim 1 , wherein the first electronic lapping guide is connected to the second electronic lapping guide through a first via and the second electronic lapping guide is connected to the third electronic lapping guide through a second via.
4. The magnetic read transducer of claim 1 , wherein the first read sensor is separated from the second read sensor by a first internal magnetic shield and the second read sensor is separated from the third read sensor by a second internal magnetic shield.
5. The magnetic read transducer of claim 1 , wherein the first read sensor and the second read sensor are separated by a first distance in a down track direction and the second read sensor and the third read sensor are separated by a second distance in the down track direction, wherein the first read sensor, the second read sensor, and the third read sensor are offset from one another in a cross track direction that is perpendicular to the down track direction, and wherein a width of the first read sensor overlaps with a width of the second read sensor in the cross track direction, and wherein the width of the second read sensor overlaps with a width of the third read sensor in the cross track direction.
6. The magnetic read transducer of claim 1 , further comprising a first read shield and a second read shield, wherein the first read sensor, the second read sensor, and the third read sensor are between the first read shield and the second read shield in a down track direction.
