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 slider comprising:
a read transducer comprising a plurality of read sensors distributed along a down track direction and offset in a cross track direction that is perpendicular to the down track direction;
at least one electronic lapping guide associated with the plurality of read sensors to control lapping of the plurality of read sensors, the at least one electronic lapping guide configured to provide at least one signal, wherein the lapping of the plurality of read sensors is terminated based on the at least one signal from the at least one electronic lapping guide, wherein the at least one electronic lapping guide comprises a plurality of electronic lapping guides; and
a plurality of vias, wherein each of the plurality of electronic lapping guides is connected to an adjacent one of the plurality of electronic lapping guides via one of the plurality of vias.
2. The slider of claim 1 , wherein each of the plurality of electronic lapping guides is associated with one of the plurality of read sensors.
3. The slider of claim 1 , wherein each of the plurality of electronic lapping guides is coplanar with the plurality of read sensors with which the each of the plurality of electronic lapping guides is associated.
4. The slider of claim 1 , wherein at least a portion of the plurality of electronic lapping guides are electrically connected in series.
5. The slider of claim 1 , wherein at least a portion of the plurality of electronic lapping guides are electrically connected in parallel.
6. The slider of claim 1 , further comprising at least one common pad to which each of the plurality of electronic lapping guides is connected either directly or through other ones of the plurality of electronic lapping guides.
7. The slider of claim 6 , wherein the at least one common pad comprises no more than two common pads for the plurality of electronic lapping guides.
