Optical Record Player

 Scanning laser replaces needle in phonograph

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).

       good idea but not all for the car thing unless they make new mobile optical phonographs [+]

       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.

       So can you actually buy one? How much? I wasn't able to find the article you described.

       Bring money. The prices are non-trivial.

       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.

       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.

       Ian, that's a good one. A really good flatbed scanner might work, too, with the right software.

       I wonder if all these hi-tech devices would cope with the double groove on the Monty Python Matching Tie and Handkerchief Gift Set?
