摘要：

In this paper we use a two-photon technique to record data points on bisazobenzene containing films The recording data points are evidently polarization dependent It is found that the recording data points can be erased by the linearly polarized light whose polarization direction is perpendicular to that of the recording beam and then in the same region new data can be rewritten after erasing In addition the recorded data can also be erased completely by the circularly polarized light Compared with linearly polarized beam the circularly polarized light is a better choice for erasure as no main orientation is regained after erasing rather than reorientation (C) 2010 Elsevier B V All rights reserved
