提出了一种新的光致变色可重写存储介质无损读出方法。当介质在使用λ1激光器的写入过程中具有热阈值时，使用在λ1和λ2处具有发射线（对应于两种异构体的吸收带）的两个激光器进行读取，可以保持信号强度恒定。通过使用光致变色二芳基乙烯介质，可以在不破坏记忆的情况下读取超过 106 次。
A new nondestructive readout method was proposed for photochromic rewritable memory media. When the medium has a thermal threshold in the writing process with a λ1 laser, reading using two lasers having emission lines at λ1 and λ2, which correspond to absorption bands of the two isomers, makes it possible to keep the signal intensity constant. Reading more than 106 times without destroying the memory was achieved by using photochromic diarylethene media.
