Slider with aluminum compound fill
Embodiments disclosed herein generally relate to a magnetic device. The magnetic head of the magnetic device includes structure for protecting the media facing surface (MFS). The protective structure, which may be referred to as an air bearing surface overcoat (ABSOC) structure, includes an aluminum containing compound that is disposed on the slider and head. The ABSOC also includes a silicon containing compound and a carbon layer disposed thereover.
1. A magnetic device, comprising:
a slider having a surface for facing a magnetic disk;
a magnetic head coupled to the slider, wherein the magnetic head has an air bearing surface for facing the magnetic disk, wherein a notch is formed between the slider and the magnetic head, and wherein the notch is filled with an aluminum containing compound layer;
a read sensor disposed in the magnetic head;
a write element disposed in the magnetic head; and
an air bearing surface overcoat structure disposed on the air bearing surface, wherein the air bearing surface overcoat structure comprises the aluminum containing compound layer and a silicon containing compound layer, wherein the silicon containing compound layer is in physical contact with the read sensor and the write element.
2. The magnetic device of claim 1 , wherein the aluminum containing compound layer comprises aluminum nitride.
3. The magnetic device of claim 1 , wherein the aluminum containing compound layer comprises aluminum oxide.
4. The magnetic device of claim 1 , wherein the air bearing surface overcoat structure further comprises a layer comprising carbon disposed on the silicon containing compound layer.
5. The magnetic device of claim 4 , wherein the silicon containing compound layer comprises silicon nitride.
6. The magnetic device of claim 4 , wherein the aluminum containing compound layer has a thickness of less than about 2 nm.
7. The magnetic device of claim 4 , wherein the silicon containing compound layer has a thickness of between 1.0 Angstroms and 6.0 Angstroms.
8. The magnetic device of claim 4 , wherein the layer comprising carbon has a thickness of between 8 Angstroms and 18 Angstroms.
