摘要
It is well known that the optical pick-up(OPU)plays a very important role in optical storage system.And the quality of OPU can be measured by the characteristics of OPU read-out spot for high density optical storage.This paper introduces the design principle and method in optical data storage.And it mainly contrives the optical path for the whole system.At the same time it proposes the design method for important optical elements.At last it introduces the parameters of collimator lens and objective lens for DVD.
