Latest Patents

One of his latest patents involves magnetic recording media that includes permanent structures of aligned acicular particles. This innovation aims to identify and authenticate media effectively. The patent describes a structure that offers an improved remanence difference signal. Additionally, it outlines methods for creating and examining such structures. The arrangements of these media, along with record and read-out apparatus, allow for information to be recorded and retrieved without interference from structural remanence differences. This media is particularly useful for security documents, such as credit cards. Another patent details a method of printing where magnetic particles dispersed in ink are selectively oriented before printing. This process involves aligning the particles on a carrier while the ink is in a low viscous state, with printing occurring when the ink reaches a high viscous state. The viscosity change is achieved through the selective application of heat.
