A ∼5-μm-thick stretched sheet of a vinyl chloride–vinyldene chloride copolymer containing a suitable polymethine dye providing an optical density of 1–2 at 823 nm has been used to record ∼3μm-diameter relaxed spots, produced with pulses of 250 μs or longer from a 5-mW GaAlAs laser operating at 823 nm. The spots have been observed under polarizing microscope. It is proposed that this demonstrates a principle that could be used for recording and retrieval of information by a laser beam, using a stretched polymer as the storage medium.
