Methods for directing an optical beam and for making an apparatus for directing an optical beam are described. In one embodiment, the recording layer includes at least two layers deposited by using a reactive sputtering method under an oxygen-containing atmosphere at a deposition rate larger than the second recording layer which is formed on the first recording layer while depositing the first recording layer on the intermediate layer. The mixture is then injected at a controlled flow rate into an electric field to cause the mixture to at least partially form fine fibers that have an average diameter of less than about 1000 nanometers. The distal end includes at least one end rib disposed about an inner circumference thereof.
