Post Subject: A confusion.Posted by Romy the Cat on: 10/12/2015

This weekend I played some records and was kind of confused. In my mind I went to this conversation and was sickened with the fact that “people do not understand obvious”. Then took my SME arms and pulled the anti-skating wait down with my head. The arm went toward to the side of the record. “What the hell” - I said.

For the new couple of housrs I examined the issues for all possible sides and read a few paper on the subject:

www.audiomods.co.uk/papers/Oakley_skatingforce.PDF

From what they say and from what how my arms are made Wellington for sure is correct: the skating force moved an arm toward to the mid of the record. It was for years my believe of very opposite, well it looks like I was wrong.

However, for all intenede porpoise my analog setup functions poorly and all geometrical and sonic issues are worked up. I for years been operated under look like wrong perception of skating and my understanding of reasoning of skating have very direct relation with sonic practicality of arm setup. Despite that it might be wrong but I am still a believer that skating is a circumference force or the force of rotating subject applied to the tangent of circle drawing the subject away from the axis. In English it frequently call centrifugal force but I think the circumference force is more accurate. The circumference force explains why different amount of anti-skating is necessary at beginning and in the end of the record: the local speed of the needle in the grove is higher and therefore the circumference tangent is higher in the end of the record.

So, even there are very objective reason to presume that I am wrong but I still chose to believe that anti-skating force pushes the needle toward to the edge of record. If for whatever reason it does not then it would be a clear evidence that Nietzsche was right and God is dead.
