Abstract

Claims (88)

1. A method for manufacturing a reader/writer, comprising:

providing a substrate;

forming an undercoat over the substrate;

forming a first shield over a portion of the undercoat;

forming a first reader lead over the first shield;

forming a read sensor over the first reader lead;

forming a second reader lead over the read sensor;

forming a first pole/second shield over the second reader lead;

forming a mid coat over the undercoat and a portion of the first pole/second shield;

forming a coil over the first pole/second shield;

forming a second pole over the coil;

forming first and second leads connected to the coil;

forming an overcoat over the first and second leads; and

forming a pad stack over the mid coat and not in the mid coat including:

a pole selected from a group consisting of the first pole/second shield and the second pole;

a lead selected from a group consisting of the first and second reader leads and the first and second writer leads;

a pedestal connected to the pole and lead; and

a pad connected to the pedestal.

2. The method as claimed in claim 1 , wherein forming the pad stack forms the pole on the mid coat.

3. The method as claimed in claim 1 , wherein forming the first and second reader leads forms the first and second reader leads distal from the substrate proximate the pad stack.

4. The method as claimed in claim 1 wherein forming the first and second writer leads forms the first and second reader leads distal from the substrate proximate the pad stack.

5. The method as claimed in claim 1 wherein forming the first shield and the first pole/second shield forms the first shield and the first pole/second shield distal from the substrate proximate the pad stack.

6. A method for manufacturing a reader/writer, comprising:

providing a substrate;

forming an undercoat in contact with the substrate;

forming a first shield in contact with a portion of the undercoat;

forming a first reader lead in contact with the first shield;

forming a read sensor in contact with the first reader lead;

forming a second reader lead in contact with the read sensor;

forming a first pole/second shield in contact with the second reader lead;

forming a mid coat in contact with the undercoat and a portion of the first pole/second shield;

forming a coil in contact with the first pole/second shield;

forming a second pole in contact with r the coil;

forming first and second leads connected to the coil;

forming an overcoat in contact with the first and second leads; and

forming a pad stack in contact with the mid coat and not in the mid coat including:

a pole selected from a group consisting of the first pole/second shield and the second pole;

a lead selected from a group consisting of the first and second reader leads and the first and second writer leads;

a pedestal connected to the pole and lead; and

a pad connected to the pedestal.

7. The method as claimed in claim 1 , wherein forming the pad stack forms the pole in contact with the mid coat.

8. The method as claimed in claim 1 , wherein forming the first and second reader leads forms the first and second reader leads above the mid coat proximate the pad stack.

9. The method as claimed in claim 1 wherein forming the first and second writer leads forms the first and second reader leads above the mid coat proximate the pad stack.

10. The method as claimed in claim 1 wherein forming the first shield and the first pole/second shield forms the first shield and the first pole/second shield above the mid coat proximate the pad stack.

11. A reader/writer, comprising:

a substrate;

an undercoat over the substrate;

a first shield over a portion of the undercoat;

a first reader lead over the first shield;

a read sensor over the first reader lead;

a second reader lead over the read sensor;

a first pole/second shield over the second reader lead;

a mid coat over the undercoat and a portion of the first pole/second shield;

a coil over the first pole/second shield;

a second pole over the coil;

first and second leads connected to the coil;

an overcoat over the first and second leads; and

a pad stack over the mid coat and not in the mid coat including:

a pole selected from a group consisting of the first pole/second shield and the second pole;

a lead selected from a group consisting of the first and second reader leads and the first and second writer leads;

a pedestal connected to the pole and lead; and

a pad connected to the pedestal.

12. The method as claimed in claim 1 , wherein the pad stack has the pole on the mid coat.

13. The method as claimed in claim 1 , wherein the first and second reader leads are distal from the substrate proximate the pad stack.

14. The method as claimed in claim 1 wherein the first and second reader leads are distal from the substrate proximate the pad stack.

15. The method as claimed in claim 1 wherein the first shield and the first pole/second shield are distal from the substrate proximate the pad stack.

16. A reader/writer, comprising:

a substrate;

an undercoat in contact with the substrate;

a first shield in contact with a portion of the undercoat;

a first reader lead in contact with the first shield;

a read sensor in contact with the first reader lead;

a second reader lead in contact with the read sensor;

a first pole/second shield in contact with the second reader lead;

a mid coat in contact with the undercoat and a portion of the first pole/second shield;

a coil in contact with the first pole/second shield;

a second pole in contact with r the coil;

first and second leads connected to the coil;

an overcoat in contact with the first and second leads; and

a pad stack in contact with the mid coat and not in the mid coat including:

a pole selected from a group consisting of the first pole/second shield and the second pole;

a lead selected from a group consisting of the first and second reader leads and the first and second writer leads;

a pedestal connected to the pole and lead; and

a pad connected to the pedestal.

17. The method as claimed in claim 1 , wherein the pad stack has the pole in contact with the mid coat.

18. The method as claimed in claim 1 , wherein the first and second reader leads are above the mid coat proximate the pad stack.

19. The method as claimed in claim 1 wherein the first and second reader leads are above the mid coat proximate the pad stack.

20. The method as claimed in claim 1 the first shield and the first pole/second shield are above the mid coat proximate the pad stack.
