Hi:
I fantasize about a different type of DVD technology.
Current DVD equipment burns pits into DVD discs. The burn "marks" the
disc with 1s and 0s. The DVD player then reads the disc. Laser light
reflected is 1, while laser light going through the disc indicated 0s.
I have a different design in mind. The discs are as thick as regular
CDs, DVDs, and LDs. The diameter of the disc, however, is approximately
that of 33-speed phonographs. The hole in the middle of my disc is
bigger than the hole in the middle of a CD in the same proportion of
which a phonograph disc is bigger than a CD. The chemical content of
the disc is slightly different from that of currents DVDs. My DVD disc
contains a layer of chemical that reacts to 400 nm light. A 400 nm
black light laser can make patterns on that layer of my DVD disc.
Visual information [images, colors, light] is fed into a digital video
camera. The digital video camera converts this analog visual
information to digital information. This information is passed on to
the recording-laser. The recording-laser is high-powered 400 nm black
light laser. The laser shines pulses of 400 nm light on to the disc.
The pulses of laser light represent digital video information. These
on/off pulses of light create on/off patterns on the disc. Unlike
current DVD-recorders which rely on laser heat to burn pits on the
disc, mine uses 400 nm black light pulses create on/off pits on the
photo-reactive disc layer [which reacts specifically to 400 nm light
while ignoring all other wavelength of light]. The playback is done by
a low-powered 400nm black light laser. This laser shines a continuous
400nm black light on the disc. In doing so, it is able to read the
on/off patterns on the disc. While the playback-laser reads the
patterns, the rest of the equipment converts the information back to
video which can be displayed on a screen.
The recording-laser in my design is the same size of the
recording-lasers in current DVD recorders.
The playback-laser in my design is the same size of the playback-lasers
in current DVD players.
My design uses bigger discs because the bigger the disc, the more data
it can store [considered the recorded patterns are of the same size as
those in current DVD discs - which they are]. Current DVDs don't use
video that is linear PCM. Mine uses linear PCM video. My linear-PCM
video is exactly like the audio .wav format, except the signals are
video and not audio. It is the video *equivalent* of the WAVE format.
Linear PCM requires more storage space than conventional digital video,
which is why my design needs bigger discs.
I am making this for sole visual entertainment. Not for movies, audio,
or stories. No audio at all. This is for psychedelic visual effects in
virtual-reality only.
I would like to use 3 dimensions of pixels -- for width, height, and
depth. 1,000,000 pixels for width, 10,000,000 pixels for height, and
1,000,000,000 pixels for depth. There should be 100,000,000 bits per
pixel.
The sample rate should be slow enough to get a bit rate of 1 bit per
second.
bit rate = sample rate X bit resolution X pixels
let "s" stand for sample rate
1 = s X 100,000,000 X [1,000,000 X 10,000,000 X 1,000,000,000]
1 = s X 100,000,000 X [10,000,000,000,000,000,000,000]
1 = s X 1,000,000,000,000,000,000,000,000,000,000
s = 1/1,000,000,000,000,000,000,000,000,000,000
s = 0.000000000000000000000000000001 Hz
sample rate = 0.000000000000000000000000000001 Hz
In a minute this would result in 60 bits used in the disc. 3600 bits in
an hour.
This would be perfect for virtual-reality.
I like my discs to be able to store exactly 1 GB each. The storage
should be one-sided. Store on one side of the disc. Label the other
side.
Any assistance would be appreciated.
Thanks,
Radium
