which side of the groove is which?

Looking down at the record, which side of the groove is the "left" side?

In other words, is it the side of the groove closest to the spindle that carries the left channel of the recording, or is it the side of the groove closest to the record's edge?

You'd think this would be easy to look up, but I've been using Google for a few hours and come up with nothing. I'm getting a bit of left-side bias in my playback, and can't tell if I should increase or reduce my anti-skating force.

Thanks for any advice.

Re: which side of the groove is which?

IIRC, when you are looking from the front of the turntable, the groove on the right (ie the outer groove - closest to the edge) is the right channel, and the groove on the left, (ie the inner groove - closest to the centre) is the left channel.

Or, if you were in the cartridge head facing away from the pivot and looked down, the right channel is on the left and the left channel is on the right.

Buddha's recollection is spot on. The left channel is encoded in the inner groove wall, right channel in the outer groove wall.
