Vinyl records provide great quality analogue (spelling?)sound, but the scratchy records eventually damage the records and wear out.
If there was another way to read a record without actually touching it, you could preserve the record. Technology similar to optical computer mice or radar might be able to read the grooves of a record, with either digital or analogue output.
You could even have a phonograph in your car or computer (at least a 45 rpm).-- discontinuuity, Jul 29 2005 ELP turntables http://www.elpj.com/Japanese-American partnership that spent tens of millions developing the laser/optical turntable. [bristolz, Jul 29 2005] good idea but not all for the car thing unless they make new mobile optical phonographs [+]-- Sudok, Jul 29 2005 Ho Hum.
Please do a little research before posting... this is pretty baked.
"Optical Record Player" gets 26 Google hits, latest Audio Engineering Society Journal has a nice article on just this. "Optical Phonograph" gets 235.
All very expensive.-- csea, Jul 29 2005 So can you actually buy one? How much? I wasn't able to find the article you described.-- discontinuuity, Jul 29 2005 Bring money. The prices are non-trivial.-- bristolz, Jul 29 2005 Not cheap but certainly baked - I think that the Baird video/phonograph records were scanned optically when they were restored recently. I'll see if I can find a link.-- coprocephalous, Jul 29 2005 Croissant for clever thought, at least. It's not widely baked, and it certainly seems worth spending tens of millions on, at least to some people.-- baconbrain, Jul 29 2005 Ian, that's a good one. A really good flatbed scanner might work, too, with the right software.-- baconbrain, Jul 29 2005 I wonder if all these hi-tech devices would cope with the double groove on the Monty Python Matching Tie and Handkerchief Gift Set?-- AbsintheWithoutLeave, Jul 29 2005 random, halfbakery
