Magnetic media access head with metal coating
View Patent ↗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.
1. A magnetic media head for accessing magnetic media, comprising:
a base substrate configured to support a magnetic head layer;
the magnetic head layer formed on the base substrate and configured to magnetically access the magnetic media;
a nonmagnetic metallic layer formed as an outermost layer 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.
2. The magnetic head of claim 1 , wherein the metallic layer prevents contact between the magnetic head layer and the magnetic media to prevent wear on the magnetic head layer.
3. The magnetic media head of claim 1 , wherein the magnetic media comprises magnetic tape and the magnetic media head is configured to access the magnetic tape.
4. The magnetic media head of claim 1 , wherein the magnetic media comprises a magnetic disk and the magnetic media head is configured to access the magnetic disk.
5. The magnetic media head of claim 1 , further comprising:
an insulator layer formed between the magnetic head layer and the metallic layer.
6. The magnetic media head of claim 1 , wherein the metallic layer is composed of titanium, platinum, tungsten, or any other metal or metal alloy.
7. The magnetic media head of claim 1 , wherein the metallic layer is from 1 nanometer to 20 nanometers in thickness.
8. The magnetic media head of claim 1 , wherein magnetically accessing the magnetic media comprises reading data from or writing data to the magnetic media.
9. A method of operating a magnetic media head for accessing magnetic media, comprising:
providing the magnetic media head comprising a base substrate configured to support a magnetic head layer, the magnetic head layer formed on the base substrate and configured to magnetically access the magnetic media, a nonmagnetic metallic layer formed as an outermost layer 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;
positioning the magnetic media for access by the magnetic head layer; and
moving the magnetic media relative to the magnetic head layer to magnetically access the magnetic media.
10. The method of claim 9 , wherein the metallic layer prevents contact between the magnetic head layer and the magnetic media to prevent wear on the magnetic head layer.
11. The method of claim 9 , wherein the magnetic media comprises magnetic tape.
12. The method of claim 9 , wherein the magnetic media comprises a magnetic disk.
13. The method of claim 9 , wherein the magnetic media head further comprises an insulator layer formed between the magnetic head layer and the metallic layer.
14. The method of claim 9 , wherein the metallic layer is composed of titanium, platinum, tungsten, or any other metal or metal alloy.
15. The method of claim 9 , wherein the metallic layer is from 1 nanometer to 20 nanometers in thickness.
16. The method of claim 9 , wherein magnetically accessing the magnetic media comprises reading data from or writing data to the magnetic media.
