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 (12)

1. A magnetic tape access system, comprising:

a controller for a magnetic tape head;

a magnetic tape head assembly 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 magnetic tape, and a non-magnetic metallic layer formed over the magnetic head layer and disposed as an outermost layer on the magnetic tape head assembly between the magnetic head layer and the magnetic tape when the magnetic tape is positioned for access by the magnetic head layer.

2. The magnetic tape access system of claim 1 , further comprising:

a first reel configured to rotate a first corresponding reel of the magnetic tape in a cartridge enclosing the magnetic tape;

a second reel configured to rotate a second corresponding reel of the magnetic tape in the cartridge enclosing the magnetic tape;

a plurality of guides for guiding the magnetic tape laterally over the magnetic tape head assembly as the first and second reels rotate.

3. The magnetic tape access system of claim 1 , wherein the metallic layer prevents contact between the magnetic head layer and the magnetic tape to prevent wear on the magnetic head layer.

4. The magnetic tape access system of claim 1 , wherein the magnetic tape head assembly further comprises an insulator layer formed between the magnetic head layer and the metallic layer.

5. The magnetic tape access system of claim 1 , wherein the metallic layer is composed of titanium, platinum, tungsten, or any other metal or metal alloy.

6. The magnetic tape access system of claim 1 , wherein the metallic layer is from 1 nanometer to 20 nanometers in thickness.

7. The magnetic tape access system of claim 1 , wherein magnetically accessing the magnetic tape comprises reading data from or writing data to the magnetic tape.
