Pioneer LaserDisc - How It Works with Don "Mr. Wizard" Herbert

i dont fully agree, but thats partially true.

I feel like touching objects and rotating them around in your hand gives much clearer idea than viewing 2d images and 3D objects on the screen

that is true, i myself am also oldschool when it comes to physical models and stuff, but i gotta agree that digital medium has lots of potential that physical cant achieve, for example, it's easier to understand how an F1 engine works with a good 3d animation. Of course, if you're studying mechanics you should always have contact with the physical objects, but digital is an essential complement nowadays.

I guess one complements the other

+maak You watched this video on a 2d screen.

Only with CAV most LDs are CLV with 60 minutes runtime per side.

And you could say that this is Dinosaur technology...

They are digital. LaserDiscs are analogue

Yes, it is. We don't have have the equipment that could handle say the entirety of the worlds internet traffic in say real time or transmit it that quantity at that speed but yes in a single fiber optic wire you could transmit an almost infinite amount of data in an infitesimal amount of time. Granted no we cant do that but it could be possible.

thanks, I am still skeptical though

@@MatthewHolevinski You didn't answer the question. The question was can 1 wavelength carry it. Your answer was that one fiber optic wire could carry it.

@@frankcabanski9409 the answer conversationally speaking is no.

@@MatthewHolevinski Thanks.

_"These were far more expensice than videodiscs and did not survive as you could scratch the surface thus rendering the disc.useless."_ LaserDiscs are videodiscs. Of course, there were at least two stylus-based systems as well: CED and VHD. And LaserDiscs can play through scratches fairly well. It's only when it's severe enough to act as sufficient obstruction to the optics to disrupt focus and/or tracking. ---- _"DVDs improved on this because you only play one side"_ There are dual-sided DVDs, such as early releases where one side has the movie in fullscreen and the other side has the same in widescreen. Dual sided DVDs are not as common today, however. Most titles now are usually released either on single-sided RSDL DVDs or single-sided single layer DVDs. ---- _"...can fit far more data on them."_ Well, yes and no. In theory, a LaserDisc has the _potential_ to store far more data than a DVD because of greater physical area where the track is written to. And this ability increases when you use a shorter wavelength/higher frequency beam. But, to do that, you would be creating an entirely new format since this digital 12 inch disc will not be complaint with the LaserVision standard and would be incompatible with existing LaserDisc players. In practice, DVD can hold more digital data than a LaserVision formatted disc, and that's because LaserVision is an analog format. That means any digital data that is stored on the disc must be done by containing its signal within an analog subcarrier or within the video signal itself. That's not nearly as efficient as the more direct method of using EFMPlus encoding to record the digital data to a DVD.
