ABSTRACT:
A method and apparatus for providing a graphical image on an optical recording disc are described. The method includes the steps of storing a digital image in a first coordinate system as a first array of bits in a digital memory, transforming the digital image from the first coordinate system to an angular coordinate system such as polar coordinates to generate a second array of bits, and then using the second array of bits to modulate a writing beam in an optical disc mastering process to write the transformed digital image onto an optical recording disc. The digital image can be obtained alternately from an optical scanner or conventional image preparation software. The method can also include the step of editing an initial array of bits to form the first array of bits.
