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.
Claims16
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.
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.
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.
