Below is an extract from a sales pitch on a LP record that plays backwards.
Very novel.
Re the bit on more information stored in the groove ....I can't get my head around it.
Can remember reading about degrading many (many) years ago - but couldn't hear it then either.
It does make sense, but I've never noticed that the quality of sound degrades as the needle gets nearer to the inner grooves. :thinking:
The difference between 3.75ips and 15ips on a R2R is audible.
Are there any mathematicians out there able to calculate the ips differential of the inner and outer grooves on a 33rpm LP?
(Or am I misunderstanding the concept described below?)
The extract.....
"There are hundreds of pieces of music that can be played backwards ? so-called palindromes. But nobody has ever seen a long-playing record that plays backwards. Until now that is! The present LP is Tacet?s latest production ? a company that is always good for surprises regarding recording techniques. Unlike a 'normal' LP the needle is put down at the lead-out groove and moves outwards. Behind this apparent gag is nothing other than the wish to achieve the very best sound possible with the general awareness that music often begins softly and ends loudly. A great pity that this phenomenon is not taken into account when employing the usual cutting technique, for the further the pick-up arm moves towards the centre, the more information has to be stored per groove centimeter with a constant revolution speed. The result: with an increasing level of sound the high notes tend to suffer from distortion. In order to demonstrate that this undesirable effect can be compensated, the director of Tacet, Andreas Spreer, chose to put Ravel?s Bol?ro ? one of the direst examples of dynamics ? to the test. The result is 16 minutes of excitement and brilliant sound, which escalates with every millimeter that the needle progresses along the groove to its final climax."
If anyone has a copy - wouldn't mind hearing it.
