Embodiment Construction
[0018] The production method of the dynamic digital holographic DVD disc is characterized by the production method of the metal stamper of the DVD disc with the dynamic digital holographic pattern: 1. The layout art design of the holographic DVD disc mainly uses a computer for image plane design and dynamic digital holographic image coding design processing . Input the designed picture file into the dynamic digital holographic lithography system. 2. Place the master disk coated with photosensitive adhesive on the two-dimensional translation stage of the dynamic digital holographic lithography system, and record the image input into the dynamic digital holographic lithography system on the photoresist plate through computer control, and then pass through the photolithography process. The first version of the dynamic digital holographic photoresist was prepared by gel development and electroless silver plating conductive layer. 3. The first plate of dynamic digital holographic ...

Abstract
The invention discloses a production method of laser digital holographic DVD discs. The method is characterized in that the stamping production of the DVD discs comprises the metal injection stamping processing of a digital holographic graph and text relief pattern. The invention has the advantages that the colorful digital holograms are directly injected into one of the DVD discs via the prior production art of the DVD discs with the two flakes injection followed by gluing. The invention, which does not increase procedures and omits the following printing, not only provides manufacturing technology for the green environmental protection, but also reinforces the functions of encryption, anti-counterfeiting and so on, which are unique to holograms, so that the DVD discs are protected from being pirated. The invention ensures that the DVD discs are provided with the properties of anti-counterfeiting, anti-piracy and enjoyment, and incorporate the high technology with the artistry.
Description
technical field [0001] The invention relates to a method for making a dynamic digital holographic DVD disc, which belongs to the fields of optical disc manufacturing, optical information recording technology, DVD disc injection holography, laser holography and micro-nano fine processing technology, and is suitable for making a dynamic digital holographic DVD disc. Background technique [0002] DVD disc production is a digital versatile disc, and its purpose is to meet people's needs for large storage capacity and high-performance storage media. The large-capacity feature of DVD discs provides software creators with a huge space for imagination and a stage to display their talents. They can use it to develop more colorful programs, mainly used to store multimedia software and film and television programs. DVD discs have not only been widely used in civilian audio-visual fields, but also promoted the development of publishing, broadcasting, information and other industries, bu...
