Abstract
An apparatus and method for reproducing sound recordings on blank films and tapes of plastic materials in which a continuous master film carrying sinuous lines of imprint containing the sound recordings to be reproduced are pressed against a blank tape as both the master film and blank tape are moved continuously at a constant speed and in synchronism past a pressure applying station. A laser is provided to emit a very fine and precise laser heat beam to heat and soften local zones of the blank tape a fraction of a second before being aligned to receive the imprints.
