In this paper, we show the method to increase the temperature tolerance with wavelength tuning in the holographic data storage. Photopolymer media is sensitive to thermal environment so this compensation method should be required to keep low BER with the temperature change. We actually demonstrate to keep high SNR with temperature change by using the wavelength tuning blue ECLD that is under development. Also we numerically show the temperature tolerance in some compensation method i.e. the angle changing method, the wavelength tuning method, and the angle and wavelength tuning (hybrid) method.
