Abstract:
The present invention is embodied in a method for storing computer readable data on a removable storage medium, including using a first wavelength to write data to the removable storage medium, using a second wavelength to maintain radial tracking on the removable storage medium, wherein the second wavelength is shorter than the first wavelength, and maintaining axial tracking on the removable storage medium with at least one of the first wavelength or the second wavelength.
