Abstract
A magnetic device includes a write element having a write element tip and is operable to generate a first field at the write element tip. A conductor is proximate the write element tip for carrying a current to generate a second field that augments the first field. An encapsulating layer is on at least one surface of the conductor, wherein the encapsulating layer is made of a material that increases a maximum sustainable current density of the conductor to greater than about 108 A/cm2.
Claims24
A magnetic device comprising:
- a write element including a write element tip, wherein the write element is operable to generate a first field at the write element tip;
- a conductor proximate the write element tip for carrying a current to generate a second field that augments the first field;
- and
- an encapsulating layer on at least one surface of the conductor, wherein the encapsulating layer is made of a material that increases a maximum sustainable current density of the conductor to greater than about 108 A/cm2.
A magnetic writer comprising:
- a write element that generates a write field at a front surface;
- at least one return element magnetically coupled to the write element distal from the front surface;
- a conductor proximate the front surface for carrying a current to generate an assist field that augments the write field;
- and
- an encapsulating layer on at least one surface of the conductor, wherein the encapsulating layer is made of a material that increases a maximum sustainable current density of the conductor to greater than about 108 A/cm2.
A magnetic field generating assembly comprising:
- a conductor for carrying a current to generate a magnetic field;
- and
- an encapsulating layer on at least one surface of the conductor, wherein the encapsulating layer is made of a material that increases a maximum sustainable current density of the conductor to greater than about 108 A/cm2 to provide a corresponding increase in the magnetic field generated by the conductor.
