Notes:
The potential for microporous films as optical recording media is explored in this report. Irradiation of metallized films of microporous polypropylene and polyethylene with a HeNe laser produced marks having high contrast and which could be read without the aid of polarizing optics. The novel marking process involves melting, collapse of the microporous structure, and thinning of the film as the built-in strain relaxes.
