Default What would cause this in a vinyl record?

I got a vintage album that sounds great over all.

However on the lead in and between every track there is quite a lot of grove noise .....pops and clicks...... much more than "normal"

What is strange is during the songs...... even during periods of dead silence, there is no groove noise at all..... except a rare faint click here and there.

Not particularly unusual for an older record that had been handled with dirty fingers.

It's an original US pressing of "Bob Seger - Night Moves "

Yes, I have cleaned it thoroughly.

It's strange indeed.

What a coincidence, I've been thinking about trying to find that LP Lately..Played it to death in late 70's.. Great Songs throughout.

I hope someone can give a definitive reason.. Best guess is the lead in grooves are cut a different size and have collected more dirt..

^ ^ ^
Yeah.... I'm thinking along that same line....
.
Perhaps the lead in grooves are a bit shallower and a previous owners low end stylus wore them.
My stylus is now bottoming out on those shallow worn grooves?

However, if the music grooves were deeper, perhaps that stylus never wore the depth of the groove that my relatively high end end stylus now reaches......accounting for the relatively clean non distorted music?

Aren't all grooves cut at the same time for the master though?

C'mon you guys, have you never seen a record with big dirty thumb prints that cover about half the first track?

Yes but, this is not a thumb print / dirty record issue.

Jeff, read the OP carefully.

JoeDJ, what your saying is possible..

Also,Since the lead in grooves are not modulated, is it possible they wear faster or dirt presses in more permanent and if record was vacuum cleaned, the lead in grooves didn't benefit from the cleaning.. Doesn't explain the silent passages in songs having a dirt free sound..

Complete master would be cut all continuous, but lead in might be different width and/or depth..

I cant find a microscopic image showing lead in vs music groove.. Could tell a story..

We care about every issue here at diyaudio.

I would suspect it was caused by repeated manual cueing into these sections as someone listened to individual tracks many many times. If the tonearm used was not well damped (or maybe not damped at all) what you are hearing could be the result.
