Method for providing a storage device
View Patent ↗A method for providing a storage device that includes a plurality of read sensor stacks for each reader of the storage device. The plurality of 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 method for providing a storage device comprising:
providing a plurality of read sensor stacks for each reader of the storage device, the plurality of read sensor stacks being distributed along a down track direction and offset in a cross-track direction;
providing a plurality of electronic lapping guides (ELGs) for the plurality of read sensor stacks; and
lapping the plurality of read sensor stacks, the lapping being terminated based on at least one signal from the plurality of ELGs.
2. The method of claim 1 wherein the step of providing the plurality of ELGs further includes:
providing an ELG of the plurality of ELGs for each of the plurality of read sensor stacks.
3. The method of claim 2 wherein the step of providing the plurality of ELGs further includes:
forming the ELG of the plurality of ELGs coplanar with a corresponding read sensor stack of the plurality of read sensor stacks.
4. The method of claim 1 wherein the step of providing the plurality of ELGs further includes:
electrically connecting at least a portion of the plurality of ELGs in series.
5. The method of claim 1 wherein the step of providing the plurality of ELGs further includes:
electrically connecting at least a portion of the plurality of ELGs in parallel.
6. The method of claim 1 wherein the step of providing the plurality of ELGs further includes:
providing a pair of pads for each of the plurality of ELGs.
7. The method of claim 1 wherein the step of providing the plurality of ELGs further includes:
utilizing not more than two pads for the plurality of ELGs.
8. The method of claim 1 wherein the step of providing the plurality of ELGs further includes:
calculating a stripe height windage for at least a portion of the plurality of ELGs.
9. The method of claim 1 wherein the at least one signal is a composite signal from the plurality of ELGs.
10. The method of claim 1 wherein the reader is a magnetic read transducer.
11. A method for providing a storage device comprising:
providing a plurality of read sensor stacks for a single reader of the storage device, the plurality of read sensor stacks being distributed along a down track direction and offset in a cross-track direction;
providing a single electronic lapping guide (ELG) for the plurality of read sensor stacks; and
lapping the plurality of read sensor stacks to form a plurality of read sensors, the lapping being terminated based on a signal from the single ELG.
