bliss53 Posted August 31, 2009 Author Share Posted August 31, 2009 Pointy. It amazes me that this technology still sounds so good. Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted August 31, 2009 Moderators Share Posted August 31, 2009 That first pic is a normal record ? I thought the groves would be straighter or more in line and not as wavy. Quote Link to comment Share on other sites More sharing options...
skonopa Posted August 31, 2009 Share Posted August 31, 2009 Check out the pictures I found on another board. Looks like somebody dragged a needle across that record in the first picture. Look across the bottom of the picture and you could see a series of smaller grooves cut across the actual record grooves. Quote Link to comment Share on other sites More sharing options...

Groomlakearea51 Posted September 1, 2009 Share Posted September 1, 2009 I like the bacteria growing around the pointy thing....[] Feeding off the residue from all that cutting through the groves....[] Just kidding!! Quote Link to comment Share on other sites More sharing options...

Clipped and Shorn Posted September 1, 2009 Share Posted September 1, 2009 I have watched a cutting head on a Scully Lathe in operation through a microscope which most lathes have and was astonished at how irregular the grooves are. At one point the grooves even appeared to collide. The engineer said this was normal. Such is life in the analog world. http://www.hrsrecords.com/index.html c&s Quote Link to comment Share on other sites More sharing options...
dollar bill Posted September 1, 2009 Share Posted September 1, 2009 Some great shots here: http://www.micrographia.com/projec/projapps/viny/viny0100.htm I will have to fire up my USB microscope that I usually just use to check stylus tips and try and snap some shots of my Telarc 1812 pressing. You can see the almost 90 degree turns when the Cannons kick in, without magnification! I've only had one cart/styli/arm combo that can reliably track it, but no speaker to properly reproduce...yet.

DTLongo Posted September 4, 2009 Share Posted September 4, 2009 "Pointy. It amazes me that this technology still sounds so good." Yep, back in the day we had our trusty little hand-microscopes to inspect stylus wear and records and that's what LP phono grooves do look like. Nowadays my turntable is a modest Audio-Technica with a USB output to dub into digital some favorite old LP's I've kept, a project I get to infrequently. It IS a wonder that that old electromechanical analog LP technology could sound as good as it did. It is still highly audiophile-seductive to see a record quietly spinning and the stylus and tonearm tracking it while the sound comes gloriously out of my Klipschorns. CD's spinning invisibly and MP3's doing their thing just don't evoke the same visual + sonic "romance." Of course one remembers the drawbacks, too. Clicks, pops and scratches, dirty LP's, worn styli, turntable wow, flutter and rumble, vibration feedback and all that. Still... The below Rodrigues cartoon pertains, hope you enjoy.

seti Posted September 4, 2009 Share Posted September 4, 2009 Ever since the Digital worms came along in the early eighties the Record Groves seem to have been dying off. Yeah but lately I have been scoring some very pristine vinyl. It is great to find a collection that has been loved and not stacked in the attic or basement. My Garrard 301 plinth project is ramping up and I should have a killer TT running by Christmas. I am very psyched. Quote Link to comment Share on other sites More sharing options...

Records are cut linearly so it does make sense to playback that way. I have often wondered why they all weren't like this from the beginning.

Because when you take $50,000 worth of technology and try and boil it down to a sub $500 unit, sacrifices are made. When they are working right, consumer level linear is great, but they rarely are and time is not kind to them. Too many moving and non replaceable parts, constant tweeking, for my liking.
