Title: Hirotsugu Suzuki and Holographic Printing Technology.

Introduction

Hirotsugu Suzuki is an inventor based in Chiba, Japan, whose patent work includes technologies for producing and recording holographic images. He is associated with Sony Corporation and is credited with 13 patents.

Latest Patents

One of Suzuki’s latest patents, “Apparatus and Method for Producing Print,” describes a system for making prints from holographic recording media. The apparatus conveys a strip of recording medium, cuts out a section containing a holographic image, and combines it with a mounting and protective film. Its components support the handling, positioning, and lamination of these materials.

Another patent, “Cartridge for Hologram-Image Recording Medium and Cartridge Including Braking Mechanism,” concerns a light-shielding cartridge for holographic recording media. The cartridge holds the medium on a core and feeds it through an opening to a recording apparatus. A braking mechanism applies resistance to the core to help control the medium as it is unreeled.
