If Nasa would send out Voyager 1 today. Do you think they would put that same disc on it?

I think probably the same one... it can be played without power, as it has grooves on it's surface that physically work; DVD, Flash drives - you'd need to download and decipher the information - and, in electronic format, I'm not sure how long the drive would maintain the information among cosmic rays.

It has been doing quite fine in the last 50 years with its good old VHS Tape

What did you want ? A Grand Piano and Captain Kirk playing it ?

Anyway, our Radio Signals are travelling a lot faster than any Man Made Craft

The idea is to have a device that (we hope) ANY intelligent species will be able to easily figure out how to read.

The disc is good because you don't need elaborate devices to figure out that it has a single groove that wiggles, and that the information is contained in the "wiggling".

Anything more complicated, and you risk that whoever finds it can't figure it out. For example, Earthlings are already giving up on DVDs; soon, we'll abandon flash drives. Disc, on the other hand, keep coming back in style (because they are really "extremely low tech"). Just look at how many musicians are going back to vinyl discs.

The same way you can remember what a person looked like, with images on a flash drive, on a DVD or (3000-year old technology) turning the image into a statue. Statues are still popular because of their simplicity: no amount of "modernity" makes them difficult to understand. If you find an old statue of Romulus (founder of Rome, 2700 years ago), then you know what he looked like, just by looking at the statue. No special equipment is needed.

Carl Sagan devoloped that specifically so whoever finds it will be able to figure out to use it.

Digital data is a a lot harder to manage (for the same goals), for example we currently use binary based computers but there are other ways to achieve the same thing.

No!!

There have been so many advances and changes on the Earth since 1977 that there would be differences to the disc.

Much of the information contained on Voyager's disc would however be added to the new disc such as the way we look and our position on the Universe.

The disc was chosen as the most reliable technology. Electronics would deteriorate surprisingly quickly, and become totally unusable within a few decades. Something like a DVD would be ok, since the disk pits wouldn't be erased like a flash drive would be over time.
