The record plays very good but don't like the bump when I drop the needle. There's no way I would play this on my main rig.
We dedicated an episode on our YT channel to flattening records.
I tried putting it on my clothes dryer with my tt glass platter and then some added weight on that but my dryer didn't get warm enough.
What did work was putting on my warmest component which is my Cary Cinema 11a and left it all day. Didn't need added weight besides the tt platter and took out about 80% of the hump.
Probably not so great for the 16-year-old Cary but it doesn't have vents on top of the unit and it seems to have held up just fine.
I don't use one, but one would think one of those periphery rings which weighs down the outer rim of the record might work. They are quite expensive, however, about $500.
Yes, should solve the problem ... but they also - unless you have a TT with a 'floating' bearing shaft - cause the bearing shaft to press down upon the thrust plate with a lot more force ... leading to increased wear.
I suggest flattening the LP is a better solution.
I had two pieces of 1/4 inch plate glass cut at my local glass shop.
Clean them thoroughly.
Clean the record as best you can.
Put the record between the sheets of glass and place them in your oven at 200-250 degrees.
Turn the oven off and wait until things are cool.
I used this method on a really bad pinch warp on an LP. It flattened to record a lot, but never was able to get rid of the sharp pinch. The record was never fully playable.
Your record, in comparison, has a very modest warp. This method might work well for you.
If you need more flattening, you can raise the oven temperature a bit and/or leave the LP in the oven longer before turning off the oven.
Good luck!
... I have a glass end table and the glass platter from my Planar P3 turntable. Won't fit in the oven but possibly I could get gentle heat from a heating vent or heat gun.
I used the oven 30 years ago and saved two out of four. So, even the oven is just "sort of accurate." I also used two heavy panes of glass, but I thoroughly cleaned the records and glass before use.
If it works without heat in a few days, I would call it a miracle!
No heat and I'll leave it a couple days. The glass platter is pretty heavy. If this doesn't work I'll figure a way to apply some gentle heat.
Not familiar with the record from the bit of music, but it appears to be a standard mid-70s to 80s Chrysalis release. Finding a good used copy would probably be cheaper than buying a vinyl flattener. I briefly considered getting one myself, but dropped the idea when I thought of how few times in the last few years I pulled out an LP that was so warped it needed to be flattened (I have a collection in excess of 20,000 pieces).

toss it. life is too short for warped records.
I've tossed a few that don't play well but this one actually sounds very good even with the hump. If it works it's still a lot less trouble than cleaning the dang things.

Sense I've been going over my old records and gathering more vinyl the last few months this is the first warped record I've come across that actually plays really well. I have tossed a few. Looking for a free solution.

Yes. There is a way to fix it.
Take a look at Vinyl Flat.
You might investigate the various record flattening devices available. I have not used any but some vinyl enthusiasts have experienced very effective results. Also, I believe some companies offer a flattening service if you do not want to purchase a device.
Back in the old days, before record flattening machines were invented, the recommended method was to:
* get hold of 2 sheets of tempered glass, 1/4" thick and just over 12" square
* make a sandwich: glass / LP / glass
* switch on your oven to 125 deg F
* put the sandwich in the oven for 4 hours (from cold)
* leave to cool down overnight.
These days ... I use a 'RecordPi'; it works very well. :-))
As most here must know, there are many vinyl flattening variations on the internet that use two panes of window glass and sunlight , I can't imagine why one would need tempered glass with such moderate temps. but I am hardly an expert, just read a lot.one of the variations that appealed to me was to heat the oven to temp, turn it off, and insert the sandwich, then let everything cool. no chance of thermal damage.
in Van denHuls paper posted on the internet , he mentions using butcher paper between the glass and vinyl. the main thing I got from his paper was his absolute emphasis on reducing moving mass in the cantilever as the primary cartridge design goal. he also suggests automobile valve springs as diy isolation devices for a turntable platform. maybe someone could explain that to me, I would think valve springs are too stiff , but I don't know the frequencies they might effect
certainly if someone asked me to pick between me and Van DenHul for advice, I wouldn't pick me.personally , the only warped record I ever flattened was by accident, " choice cuts" by the pure food and drug act, a pretty good album hippie days album. it was jammed into overly tight storage and ignored for years because of a ski jump warp on the first song. . when I decided to give it a spin, it had been perfectly flattened I knew the storage had grown a little tight over time , but didn't realize it had become industrial strength tight. .
I can see dropping a couple hundred dollars on a gizmo if you have a constant need. I never had enough records pass through my hands where it was even a problem. probably because record stores don't put warped records on the shelves , and I check everything anyway . I also cut open new records right away , so the tight shrink wrap that I prefer to leave on can't distort the surfaces over time.

just returned from googling my suggestions below. most get results without heat, and that worked for me, although unintentionally , because my records were stored so dang tight.
it seems the best was is to skip the heat, hit up a glass shop , and you're set.
I'll do what I can . the Van DenHul paper, the guy behind the grasshopper cartridge and the audio company , might still be online, along with other online methods . but here goes.you get two panes of common window glass, some run masking or other tape around the outside edges to prevent accidentally cutting their hands, place the record between the panes , affix them together, some use tape, wrap it with twine , string, what ever works, most just use a weight, the idea being to have two parallel surfaces to guide the record back to the "Memory" of the original molecular lattice arrangement created in the pressing machine when manufactured. the idea being to avoid melting the original bond organization forming the flat record.
most just set it in the sun to get a gentle warming and watch it so that it doesn't get too hot, and that's it .
I think the heated oven method suggests 160 degrees, but my memory is not perfect on that, you better look it up ( correction, I did look it up and 125 is the temp.. but no heat is more often successfully used) but I do like that the heat load is descending until perfectly cool, for safety., and that you can just let it cool overnight on its ownVan deHul was the only one to suggest adding butcher paper into the sandwich, I think parchment paper with any coating away from the record would be easier to obtain than his suggestion of butcher paper. most methods don't use paper, just glass
As stated, I have never done it myself, but it exploits the same properties intrensic in record vinyl , in the same way, that the electric flatteners do, you just don't have to buy another heat source and controls when you already have the sun or the kitchen oven. plus , unless you break the glass, it will never fail , lasting as long as the records , without question.
I'm going now to google window pane record flattening, just to check my work.
all the best. I had occasion to visit Alaska, mostly back in my sailor days, hauling oil or containers, and always enjoyed it immensely.
