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