Title: **Innovator Spotlight: Kimiaki Yoshino**
Introduction
Kimiaki Yoshino is a prominent inventor based in Yawata, Japan, recognized for his significant contributions to the field of optical information recording. With a total of six patents to his name, his innovations exemplify the cutting-edge developments in optical recording technology.
Latest Patents
Among Kimiaki Yoshino's notable patents, the first describes a method for recording optical information in high density. This innovation involves an optical recording medium that includes a substrate and a recording layer consisting of at least two J-aggregates of dyes. These dyes can include photochromic options or other types capable of forming aggregates with narrower absorption spectral ranges compared to their original forms. By using a single laser beam spot, multiple information bits can be recorded within the layer, which is constructed either using a Langmuir-Blodgett (LB) film method or a technique allowing fluidization of a dye solution laterally across the substrate.
His second patent pertains to another optical recording medium developed through the combination of spiropyrane containing a long alkyl chain and methods such as the Langmuir-Blodgett film or spin coating. This medium undergoes a process where the spiropyrane is photo-isomerized to photomerocyane upon UV irradiation, followed by stabilization of J-aggregates under mild heating. The rewritable nature of this medium, which can preserve recorded information for over 5,000 hours, highlights its potential applications in data storage.
