Abstract
We have proposed a compatible pickup for HD DVD/DVD/CD systems, which uses a blue/red/IR multi beam laser unit and a single sensor unit. The optical path of the DVD system is aligned to that of the HD DVD system to share one sensor area. Experimental results confirm the practicality of the proposed pickup
