Yes, magnetic levitation turntable!
I've been slowly ripping my older albums to CD (has been a while since I did any, takes a while to rip them and then break up an album side to individual MP3s). But I rarely play them as an album.
I wonder how they screen the pickup?
That is pretty funny and artsy. I like it. I thought by now you could just set the record down on any surface and take a picture of it with a high resolution camera to read the surface all at once, and just encode the hills and valleys of the grooves into audio. Same thing with CD's. But then again I'm still waiting for my flying car to come in.
There's laser record players, nothing touches the record, but still plays real time.
I wonder what resolution you'd need to scan a record & store it as data?
2 channels * 16 bits/channel * 44100 samples/second * 23 minutes * 60 seconds/minute = 1,947,456,000 bits = 243,432,000 = 243.4MB for a 5 song record. Does that seem high? My 256K bit-rate sample MP3s work out to ~8MB/song, but that's with lossy compression. I don't recall how big straight ripped songs are stored as .wavs.
And then the track data would have to be put together from the circular disc somehow. Maybe a high speed laser scan of the spinning disc would be easier data manipulation-wise.
Scanning a CD would be harder, even tighter packed data to be read off with a laser.
That's just not right. ???

No prices listed for the laser record players that I could find.
Here's 4 cars that are flying now. Only 2 seaters tho. Intro ends ~ 0.52.
The 2 most car-like are ~ $250K or so I think.
It seems like there might be some difficulty keeping the tracking speed constant.
