Abstract

A spiral-shaped lamp ( 10 ) is used for disk manufacturing processes, such as curing of coating or bonding, to provide uniform intensity of UV energy to the circular disk without requiring relative motion between the disk and the lamp during the curing process.

Claims

exact text as granted — not AI-modified
1 . A system for processing a DVD comprising a pulsed lamp for directing pulse light to the DVD, the lamp having a configuration with at least one circular turn, 
 wherein the lamp is a spiral with at least two turns,    the system further comprising a contoured reflector positioned to reflect light from the lamp to the DVD, the reflector being configured to provide less light to the center of the DVD and more light to the periphery.    
   
   
       2 . The system of  claim 1 , wherein the lamp had a diameter greater than that of the DVD.  
   
   
       3 . The system of  claim 1 , wherein the lamp had a diameter less than that of the DVD.
