Abstract:
1. A method of printing on a LightScribe disc, comprising: determining whether a recordable medium is a LightScribe disc based on a first pattern corresponding to spokes provided near an inner circumference of the recordable medium using a spoke detector; determining whether a surface facing an optical pickup device corresponds to a data surface or a label surface based on whether reflection of optical light occurs on the surface or within the LightScribe disc; detecting a second pattern corresponding to an index mark; synchronizing with a spoke corresponding to position “0”, the spokes providing location information of an index mark, a saw teeth area, a media ID area, and controlling a speed of rotation of the LightScribe disc; detecting media ID on the Lightscribe disc; and printing on the label surface of the LightScribe disc, wherein the label surface is divided radially into a plurality of areas, and a first focus point for the optical pickup device is determined for each of the plurality of areas, and the first focus point is used in its corresponding area of the label surface during printing.
