Title: Kazuhisa Morimoto: Innovator in Optical Recording Technologies
Introduction
Kazuhisa Morimoto is a prominent inventor based in Settsu, Japan. He has made significant contributions to the field of optical recording technologies, holding a total of 12 patents. His innovative work focuses on methods and mediums for recording optical information, showcasing his expertise in this specialized area.
Latest Patents
Morimoto's latest patents include a method for recording optical information in optical high density. This invention describes an optical recording medium that comprises a substrate and a recording layer of at least two J-aggregates of dyes formed on the substrate. The dyes utilized may be photochromic or other types capable of forming aggregates with narrower absorption spectral ranges than the original dyes. A plurality of information bits can be written in the recording layer by the irradiation of a single laser beam spot. The recording layer is formed using an LB film method or a method that fluidizes a dye solution horizontally to the substrate surface. Additionally, he has developed an optical recording medium prepared using spiropyrane, which contains an alkyl chain with at least ten carbon atoms. This medium is structured to undergo photo-isomerization when irradiated with UV light, allowing for rewritable capabilities and the retention of recorded information for over 5,000 hours.
