Abstract: A record media transporting or dispensing mechanism comprising a first moving endless belt system having an advance side and a return side and also having a diversion point therebetween. The mechanism also includes bill cassettes and pickers for supplying record media to the advance side and also for cooperating with the advance side to transfer the record media to the diversion point. Also included is a second moving endless belt system cooperating with the return side to provide an entry area and a discharge area with regard to the record media and also for transporting record media from the entry area to the discharge area. A buncher is used for receiving and accumulating the record media received from the diversion point and a diverter, located at the diversion point, is used for diverting the record media into the entry area or the buncher accumulating in response to a control signal.

Abstract: A method and apparatus for embossing diffraction gratings on a record medium is disclosed. The diffraction gratings are embossed on a strip of aluminized plastic which is later imbedded in a record medium like a "credit card" for use in a security system which utilizes data recorded in the form of diffraction gratings and data recorded in magnetic stripes on the card. The apparatus utilizes embossing masters in the form of "type bars" or grating bars which are selectively indexed to an embossing station where the embossing takes place under controlled heat and pressure conditions. A special method or layout scheme is used in laying out the embossing masters on the grating bars.
