Abstract
A data storage device is introduced. The data storage device comprises a write head. The write head comprises a heating element and a tip. The write head scans a data storage medium, wherein in an operation mode of the data storage device the tip is in contact with a surface of the data storage medium and heat is applied to the tip by means of the heating element. In order to achieve a good thermal contact between the tip and the data storage medium, the tip comprises a carbon element that is at least partially in contact with the surface in that operation mode. Such a write head can also be applied in the field of scanning probe lithography.
Claims15
Data storage device, comprising:
- at least one write head, the write head comprising a heating element and a tip;
- and
- a data storage medium, wherein in an operation mode of the data storage device the tip is in contact with a surface of the data storage medium and heat is applied to the tip by means of the heating element,
- wherein the tip comprises a silicon tip body and a carbon nanotube element having a first portion extending in a first direction and a second portion extending in a second direction, wherein the first direction is substantially perpendicular to a surface of the heating element and the second direction is substantially parallel to a surface of the silicon tip body, and wherein the first portion of the carbon nanotube element is at least partially in contact with the surface of the data storage medium in the operation mode.
A write head, comprising:
- a heating element;
- and
- a tip for acting on a medium in an operation mode, wherein the tip is in contact with a surface of the medium and heat is applied to the tip by means of the heating element,
- wherein the tip comprises a conical silicon tip body and a carbon nanotube element having a first portion extending in a first direction and a second portion extending in a second direction, wherein the first direction is substantially perpendicular to a surface of the heating element and the second direction is substantially parallel to a surface of the silicon tip body, wherein the second portion of the carbon nanotube element contacts a portion of a lateral surface of the conical silicon tip body, wherein a bend is formed in the carbon nanotube element at an apex of the conical silicon tip body, and wherein the first portion of the carbon nanotube element is at least partially in contact with the surface of the data storage medium in the operation mode.
