Adding to the vinyl ritual

Posted by Mark Kelly (M) on April 12, 2007 at 18:27:37

The bunfight below regarding the pains attendant upon the vinyl ritual prompts me to ask this:

Is there a place in the ritual for a device which allows removing the effect of off-centre pressings? If so what would you expect to pay - would $1000 on top of the price of the TT be too much?

It occurred to me that computing power which would have been a designer's wet dream in the 80s is sitting next to each of us. With the right peripherals a "computing platter" as per the Nakamichi Dragon is achievable as a plug in to a laptop. It would cost a bit more to make it stand alone.

At this stage the device is vapourware but the vapour has two parts - a modified platter which allows the record to be re-centred and a separate device which measures the adjustment required. Each side would only need to be measured once and the appropriate data recorded (!) so that the adjustment could be replicated. In theory the reduction in eccentricity would be better than 99%, eg a 2mm offset (enough to cause 1% RMS speed wobble) would be reduced to better than 0.02mm (less than 100ppm)

Jose K, I'm going to need your help handling the serial data stream.
