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.
