A storage material that is suitable for rewritable volume holographic media with a thickness in the millimeter range is presented (see figure). Writing, reading, and deleting are possible by purely optical means, and inscribed multiplexed gratings exhibit good long‐term stability. A two‐step method of optical deleting allows for more than 1000 erase–rewrite cycles without a measurable change in the material.
