This is what to do with all those AOL discs in your waste basket. A device that looks like a portable CD player but it records on them too. But not the normal way. It cuts grooves in them like a vinyl record. Then you can play DJ, or put them all in a jukebox, or copy all your favorite songs onto them
before CD's become obsolete like 8-tracks and everyone has to go buy a DVD-audio player. Groovy records might get scratched sometimes, but in the future everything else will be totally unplayable just like 8-track tapes and beta movies.
In 2103, you can still just put the needle on the record and spin!

They're just CDs that *look* like old 45s. [jivetalkinrobot, Oct 04 2004, last modified Oct 05 2004]

probably just like a real record cutter, making grooves in the plastic. I like it, but I'm concerned about the data density. |

I agree, CD is anything but permanent storage. (burnable cd anyway. a real "pressed" cd with physical dimples in the recording surface should last for a long time). It's true, you can play an old record with nothing more than a needle and a cup (and maybe a pencil to spin it on), but what's someone going to think ten thousand years from now when presented with a shiny disk full of encoded digital data? |

[Freefall] : "nice coaster"? |

Can plastic be cut this way like vinyl can? If this would work, you're a genius. |
|
| |
Oh yeah... what I meant was can CD plastic be cut the same way. Even if the density is low, you could still fit at least several minutes on a disc! |

I've seen blank CDs to buy that *look* like vinyl records [link]. |

I have heat up a needle with a match and spun a CD and made a short groove. Then the pin cooled off. I think it might work if I put thin heater wire on the needle and slowly move the tone arm while yelling into a cup that's on the tone arm. This needle I will record with is the kind for stitching. If this works then I will vibrate the needle electromagnetically with output from a radio's amplifier. The only thing I am worried about is if shreds of CD plastic are torn off by the needle and gunk it up, but the right temperature of heat in the needle might prevent that. Finally if all works well then instead of moving the tone arm by hand I will use a clock motor with a screw on it, to move a nut that's on the tone arm, to make nice grooves. If the clock motor records a buzz then I'll try something else. |

Polycarbonate is pretty hard stuff. A synthetic-diamond-tipped needle would probably be a good idea. |
|

Good idea. If not heating the needle, which would probably work, maybe you could pre-heat the CD itself. You could definately put a few minutes of music on a CD sized disk. Superb! |
