Patent ID: 7414643

Claim:
A method of printing 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 index mark, saw teeth area, 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, comprising compensating for a position error for each step/sled movement of a prescribed distance of an optical pickup device, wherein a 360 degree rotation corresponds to 20 step/sled movements of the optical pickup device such that each step/sled movement corresponds to an 18 degree rotation of a step motor and the prescribed distance corresponds to 150 μm of the step motor, wherein any position error for each step movement deviating from 150 μm is previously stored in a memory for compensating for any position error during the print step.
