Abstract

Embodiments disclosed herein provide magnetic media access heads with metal coatings. In a particular embodiment, a magnetic media head for accessing magnetic media comprises a base substrate configured to support a magnetic head layer. The magnetic head layer is formed on the base substrate and configured to magnetically access the magnetic media. A metallic layer formed over the magnetic head layer and disposed between the magnetic head layer and the magnetic media when the magnetic media is positioned for access by the magnetic head layer.

Claims (22)

1. A method of manufacturing a magnetic head for accessing magnetic media, comprising:

applying a non-magnetic metallic layer over a magnetic head layer as an outermost layer of the magnetic head, wherein the non-magnetic metallic layer is disposed between the magnetic head layer and the magnetic media and wherein the non-magnetic metallic layer remains on the magnetic head after manufacturing.

2. The method of claim 1 , wherein a base substrate supports the magnetic head layer.

3. The method of claim 1 , wherein the magnetic media comprises magnetic tape.

4. The method of claim 1 , wherein the magnetic media comprises a magnetic disk.

5. The method of claim 1 , wherein an insulator layer is formed between the magnetic head layer and the non-magnetic metallic layer.

6. The method of claim 1 , wherein the non-magnetic metallic layer is composed of titanium, platinum, tungsten, or any other metal or metal alloy.

7. The method of claim 1 , wherein the non-magnetic metallic layer is from 1 nanometer to 20 nanometers in thickness.

8. A method of operating a magnetic media head, comprising:

accessing magnetic media with the magnetic media head comprising a magnetic head layer and a non-magnetic metallic layer formed over the magnetic head layer and disposed as an outermost layer of the magnetic head between the magnetic head layer and the magnetic media.

9. The method of claim 8 , further comprising:

positioning the magnetic media for access by the magnetic head layer.

10. The method of claim 9 , wherein accessing the magnetic media comprises:

moving the magnetic media relative to the magnetic head layer.

11. The method of claim 8 , wherein the magnetic media comprises magnetic tape.

12. The method of claim 8 , wherein the magnetic media comprises a magnetic disk.

13. The method of claim 8 , wherein the magnetic media head further comprises:

a base substrate configured to support the magnetic head layer, wherein the magnetic head layer is formed on the base substrate.

14. The method of claim 8 , wherein the magnetic media head further comprises an insulator layer formed between the magnetic head layer and the non-magnetic metallic layer.

15. The method of claim 8 , wherein the non-magnetic metallic layer is composed of titanium, platinum, tungsten, or any other metal or metal alloy.

16. The method of claim 8 , wherein the non-magnetic metallic layer is from 1 nanometer to 20 nanometers in thickness.

17. The method of claim 8 , wherein accessing the magnetic media comprises reading data from or writing data to the magnetic media.
