Abstract

Mastering tools and systems and methods for forming a cell on the mastering tools are provided. An exemplary method includes emitting a first laser light pulse from a laser for a first predetermined time interval such that at least a portion of the first laser light pulse forms the cell on the mastering tool. The cell has an opening size within a range of 10-100 micrometers and an aspect ratio less than or equal to 1.25.

Claims

1. A mastering tool, comprising:

a cylindrical drum having a cylindrical outer surface and a cell in the cylindrical outer surface, the cell having a diameter of 10 micrometers to 100 micrometers and an aspect ratio of 0.5 to 1.25; and

wherein when the tool is in use, the cell will form texture.

2. The mastering tool of claim 1, wherein the cylindrical outer surface comprises a plurality of the cells, the plurality of cells having different aspects ratios from one another of 0.5 to 1.25.

3. The mastering tool of claim 1, wherein the cylindrical outer surface comprises a plurality of the cells, the plurality of cells having different opening sizes from one another of 10 micrometers to 100 micrometers.

4. The mastering tool of claim 1, wherein the cylindrical drum is constructed from steel with an outer chrome surface.

5. The mastering tool of claim 1, wherein the cylindrical drum is constructed from steel with an outer ceramic surface.

6. The mastering tool of claim 1, wherein the cylindrical outer surface comprises a plurality of the cells, the plurality of cells being randomly located on the cylindrical drum.

7. The mastering tool of claim 6, wherein the cylindrical outer surface comprises a plurality of the cells, and wherein centerpoints of the plurality of cells are randomly located within a predetermined distance range from a circumferential line extending around the cylindrical drum.

8. The mastering tool of claim 1, wherein the cylindrical outer surface comprises a plurality of the cells, and wherein the plurality of cells are randomly located on the cylindrical drum, and wherein the cells have a round shape.

9. The mastering tool of claim 1, wherein the has a round shape.

10. The mastering tool of claim 1, wherein the aspect ratio is 0.5 to 0.9.

11. The mastering tool of claim 10, wherein the aspect ratio is 0.5 to 0.7.

12. The mastering tool of claim 1, wherein the cylindrical drum has a plurality of the cells and wherein the plurality of cells have a predetermined distribution of cell opening sizes.

13. The mastering tool of claim 1, wherein the cylindrical drum has a plurality of the cells such that the plurality of cells have a predetermined distribution of position error distances within a range of position error distances.

14. A mastering tool, comprising:

an element selected from the group consisting of a cylindrical drum and a plate, wherein the element has a plurality of cells, the plurality of cells being positioned on the element such that the plurality of cells have a predetermined distribution of position error distances within a range of position error distances.

15. A mastering tool, comprising:

a cylindrical drum having a cylindrical outer surface;

wherein the cylindrical drum is constructed from metal; and

wherein the cylindrical surface has a plurality of cells, the plurality of cells having a diameter of 10 micrometers to 100 micrometers and an aspect ratio of 0.5 to 1.25; and

wherein when the tool is in use, the plurality of cells will form texture.

16. A mastering tool, comprising:

a cylindrical drum having a cylindrical outer surface;

wherein the cylindrical drum is constructed from metal;

wherein the cylindrical surface has a plurality of cells, the plurality of cells having a diameter of 10 micrometers to 100 micrometers and an aspect ratio of 0.5 to 1.25, and within a predetermined distribution being randomly located and/or having a random size; and

wherein when the tool is in use, the plurality of cells will form texture.
