Running Time for a 7" Cut ??

Once you have cut a master laquer, you have metal stampers created and have records pressed from them. Discuss manufacturing here. (Record Matrix Electroforming- Plating, Vinyl Record Pressing.)

I did a 6 minute 7 inch at 45 rpm recently. Downbeat house music with a lot of sustained deep bass sounds and of course a 4/4 bass kick driven beat. Peaks between -4 and -5 VU (0 to -1 dbm). To get any more time would mean to lower the volume even more since they are inversely related. Never cut a 7" at 33.

Guys there are standards that have been established a long time ago
I have posted them here more than once
Sure one can do as much as 6 minutes on a 7" x 45 but is is really pushing the medium to it's very limits with a whole host of issues on the final pressings that do not serve any one well
Jumping stylus as well as low fi being the most common complains once past 3.5 min max 4 is breached
Yes I know so and so did this and this other dude did this tra la la la we all heard it before
Take a look at more than the 10s of millions of records pressed over the years and point out to me a 1000 that go past the 3.5 - 4 minute mark
Than I may get converted as well
The 45 x 7" it's most likely the best format to deliver the best the vinyl record can deliver in terms of dynamics, sound quality on a small light weight package all relative of course as to the time it was "invented" Wel that was a long time ago
So why do we want to rewrite the rules?
It is certain as there has not being any improvement on the techniques so as to justify that

This is from the B Side of this release. It starts at the break in the middle of the track which is also half way through the side. So definitely in the worse part of a record (the innermost diameters of a 7").

It was a 7" release cut at 45 RPM. The tracks were each 6 minutes in lenght. Downtempo House Music. It was one of the first Master Lacquer jobs I ever cut.

http://www.deepgroovesmastering.com/audio/Downbeat_7_Inch_45_RPM_6_Minutes.zip

Obviously it isn't insanely loud. I had to trade off some volume to get the track to fit. The leed out groove was pretty tiny... Maybe one revelotion. So we pushed it to the label on this one.

I have included two minutes of the original and 2 minutes of a rip of the cut. Playback on a Technics 1200 with Orofon cart and tip. Counterweight was set all the way back. So, if it was going to skip on playback it would have under this scenario.

approx:
7min @ 33 RPM per side
4:30min @ 45 RPM per side
there is also 14min @ 33 possible or something like that,
but not for "normal" music, more speech or just accoustic gutiar...
you need also a very good pitch system,
the vms 70 pitch is not good, often problems with calibration etc.
better is vms 80 or vinylium pitch98, what I have installed in my AM32.
No problems with skipping grooves, only kissing ones ;)
for long sides, you need defenetly a perfect working pitch, or you
can do your work more often...
at this point:
thanks to vinylium switzerland for their fabalous work!

I had no major issues with this cut. No skips on playback. No overcuts. And I fit 6 minutes on a 7" at 45 RPM. All with the original VMS70 pitch/depth computer. Mine works fantastic. Possibly due to the restoration and calibration performed by Al Grundy. Your mileage may vary I suppose.

Adding to the thread for future readers-

Please try to always cut 7"s at 45. a quieter 45 sounds better than a louder 33 at these inner dimensions.

I cut 5:20 45 7" with -1dB peaks yesterday. punk
