We have proposed a compatible pickup for HD DVD/DVD/CD systems, which uses a blue/red multi-beam laser unit and an IR-LD (infra-red laser diode) chip. The optical path of the DVD system is aligned to that of the HD DVD system to share one sensor. Experimental results confirm the practicality of the proposed pickup.
