Stylus Drag

Newton's First Law of Motion:-

The velocity of a body remains constant unless the body is acted upon by an external force.

'Friction' is an 'external force'. Why do you think a motor is required to keep a platter spinning?

I personally can't imagine a platter that only weights even 5-10 pounds being slowed down enough by a short complex passage, to be bothersome.

Don't imagine it..........get a Timeline and SEE it!

Dear Nikola,
Actually the Raven is not that bad.
Using the Timeline......I found that two motors (opposed) actually kept a more constant speed than the three motors.
So that's how I now use it.
I think that stylus drag is a common factor for all belt-drive TTs....even those with string-drive and very heavy platters. Read how Dover, with his Final TT had to adjust the speed controller when the cartridge hit the vinyl?
I also had to do the same on the Raven.
In other words.....the speed of the TT is different with a cartridge tracking than without.
The TT-101 however......keeps the same speed regardless of whether there is a cartridge or not.....or even if there are multiple cartridges in contact with the record.

Incidentally......I also find that low compliance cartridges like most LOMCs.....have more stylus drag than high compliance MM s.
This may be why I hear less distortion with most MMs than I do with LOMCs?

Step into the path of a person on a bicycle, and see how much measurable speed is lost. Then try stepping in front of a freight train, and see how much the train slows. Big difference. More mass. That short heavy passage is more like the bicycle IMO.

Also, if the groove has that much information, there is probably a lot more tracking distortion problems, stylus suspension distortion, and other problems going on that would be more noticeable IMO.

If your listening to something recorded on a an analog master, there is a lot more speed variation. Their flywheel has just a tiny bit of mass. You could hear this on a $99 record changer.

You may be seeing more record slippage with the Timeline, than the actual platter speed error.

How much error does the Timeline clock and circuit have?

The hole in the records are off-center quite often. More constant speed error here too. I hear a lot more of errors on the records, in comparison to a good turntable.

You could get a custom made multimillion dollar table, but you still have the same records, with their problems.

Regarding the greater stylus drag with low compliance MC cartridges......I suspect it is also related to the higher tracking forces generally required with those over the MMs?

The logic and our hobby don't fit together. I have no clue
why the low compliance carts are produced which is the same
(in my case)as that they make no sense to me. Despite of
this (subjective) fact I own 2 or 3 of those. I know that something
is wrong with me but have no idea what is wrong
with the low compliance MC's. Can someone explain to me why
those are still produced?
