Subject: Let's bring it all back!!!<br />
Yah, I'm behind bring the <strong>CED</strong> back!!!..... Yah, what a neat idea!!!<br />
While were at it, lets also bring back the 8 track!!! Just think of how many<br />
people have 8 track players out there. They're tucked away in garages<br />
and basements, even at flea markets... We could buy the 8 track<br />
recording devices and mass produce 8 tracks....<br />
While were at it, we could also make great games like Street Fighter and<br />
Tokyo Wars for the Atari 2600. Just think of all of the neat graphics!!!<br />
Hey, think of all of the people that have old IBM 8088 computers.... We<br />
could market a a version of MYST or Sim City 2000 for them..... Then we<br />
could mass produce the Commodore 64 and TI-994A again.<br />
Okay, I think I made my point clear..... Back to <strong>CED</strong> digest......<br />
Although we'd love to have new <strong>CED</strong>'s I just don't see it as possible with<br />
CD and other laser/disc technologies.... RCA has it's own DVD player<br />
now and I think formats are getting smaller instead of larger.<br />
Later,<br />

Dave asked why the Ced disks spin so fast, i belive it is because of the 6Mhz(<br />
6,000,000 hz) or so frequency of the video + audio signal. At 33 1/3 rpm<br />
these high frequencies would not register in the grooves, because the waves<br />
of the signal are so minute that a higher surface to stylus speed is required<br />
for the cutter to engrave these high frequencies. The 33 1/3 is acceptable<br />
for audio because the highest frequency audible is around 20khz (20,000 hz).<br />
I suppose it would be theoretically possible to record video signals at 33<br />
1/3 rpm, if the laquer was of ultra-high quality, ultra-fine, to the point of<br />
being smooth on a microscopic level, used in conjunction with a precision<br />
cutting head that was exremely powerful at the high frequencies. But its a<br />
hell of a lot easier to spin the disk at 400rpms though. I belive that the<br />
disk on the voyager is nothing more than a copper Lp, if even that much, how<br />
would some alien be able to play it? was there a player on board? and ive<br />
also wondered if it would be playable after all those years of collecting<br />
cosmic dust. maybe its just a kind of hood ornament! (or belt buckle!)<br />
