teracts the inward

Ok, considering all this, which way does the tonearm move when it jumps the track? I have only ever seen a tonearm jump outward and replay the portion of the track it just played.

PJ claims it can also jump inwards. Perhaps he's referring to a pitiful portable picnic player instead of a turntable.

And there's a third type of tonearm aside from the two you mentioned. My turntable is a computer controlled laser-guided linear tracking device. The tonearm only pivots up and down, the tonearm is carried across the disc (I assume) by a worm gear and the cartridge is tangent to the spiral at all times. I don't know if such a device has an anti-skating mechanism, although when a scratch is encountered, it too jumps outward.

Is it possible it actually maintains the exact same radius and "going backwards" is due to the disc rotating under the fixed cartridge?

Hard to say, as Google Groups is useless in this regard (every one I search for takes me to the same message).

Looks pretty neat. A little overpriced.

Phil is one of those not so rare idiots that actually think that his post links are the same for everyone.

If the idiot is going to do that, then he should hunt up, and use the actual google links to a message. That way, the idiot does not have to even know that his stupid links only work for folks on his stupid ISP's servers.

Thanks for stating clearly all the stuff i used to be able to say. There have been several design for linear tracking and other compensation systems. My personal favorite is one of the laser turntables. No contact, no wear. BTW there is a very slight differential in speed of the two sides of the groove.

My goodness, he's a worse hopeless case than even I expected. Of course, I'm killfiling him on the bits that he can't change, so I didn't get to see his stupidity in its full, ahem, glory.

detecting a sound and printing the expected word! -- pbhj on /.

The concentric end grove wastes the least space on the disc. The eccentric end groove was originally used to trigger the brake on a Victrola. Perhaps 78s originally did not have a fixed-location end groove, and so had to rely on the tone arm going out to detect the end of the record (and thus stop).

Did Victrola's stop? I thought you had to lift the arm off the disk manually.
