Holo2005 Holographic Origination System
mastering system to create or originate holographic patterns for use on optical discs or on
patterns on the ID band of discs and immediately allows the data to be recorded in line in
the existing mastering system. Alternatively, a holographic pattern and a barcode can be
created simultaneously without having to make adjustments for angular positioning and
exposure and developing processes. This improves yield tremendously as handling is
eliminated and failures due to contamination and incorrect exposures in dual systems are
nonexistent.
The holograms used in discs can greatly enhance the looks of a media from a quality feel
perspective as well as provide superb authentification features that cannot be duplicated.
This process can be used to create stunning graphics unlike traditional pit art or exposure
processes used on DVD-5's and eliminates the printing process saving time and money.
Compared to origination methods used in the holographic industry where origination speed
of hundreds or even thousands of dots per second is fast, this method is 100,000% faster
reducing the time to generate a full 6 by 6 inch holographic image in under an hour.

Further Concepts:
Although the inherent process to create holograms is used for decorative purposes, the
usages can include embedding security features in withing data carrying features of an
optical disc.
In traditional optical media the data is recorded in a concentric spiral with a defined track
pitch. In between the data features referred to as land, holographic marks can be made
such that the presence of the marks do not interfere with the decoding fidelity of the system.
Since decoding of data is determined by the contrast in track of the edges of the data
features, any marks that stray in this area can cause data jitter to increase significantly and
render the data to be decipherable.
The patented process can differentiate the radial positions of the data tracks and embed the
holographic marks in between the data elements. The result is a visible watermark that do
not interfere with the playback of the disc but still provides a visual cue to the authenticity of
the original disc.
Requirements:
1. A laser beam recorder that can accept an input to the translation, rotation, and laser
beam modulation such as an Singulus AM-200 or AM Master. The input would be switched
allow data recording and holographic elements recording. The holographic modulation
system can be adapted from 1V to 5V to accommodate for the laser modulator requirements.
2. The translation accuracy needs to be less than 50 nm and precision within 10nm.
3. A separate computer to prepare the graphics and to control the holographic modulation
system.
4. The full width half max spot size of the laser beam system must be able to be controlled to
1/4 of the track pitch of the data spiral.
