Records not stored vertically for decades

@soix As you were informed earlier in the thread that you are the sole investigator of your concerns about quality of the Albums condition.

Your follow up response:

" Ok. I was mainly concerned the pressure from the weight would affect the grooves and the sound but not sounding like that’s much of a problem." 

If the Stack was quite neat, without too much edge overhang of the Albums perimeter edges between tiers, the idea of the Groove receiving compression is one that is less of a concern, as the Outer Raised Dead Wax Rim and Inner Raised Label will have been the points of loading. Hence, references being made to Ring Damage demarcation visible on Album Covers. The Grooves will have been recessed in relation to these two positions and been free from excessive force being applied.

If there has been an increased overhang of the Albums Perimeter Edges between tiers, The Likelihood the Offset in alignment is more that 50 % of the surface area of the Label diameter seems excessive, but the off set being more than the 50 % of the width of the outer Dead Wax, does seem quite viable. If this off set is seen in the stack, there is the likelihood the Grove have been exposed to  point force, where the Dead Wax was able to be compressed and add force to the Groove.

Note: Force applied will be if typical as a Storage, passed through an Albums Outer Sleeve and then the Inner Sleeve, there might even be a Outer Sleeve Protector in use as well. These layers of protection being present, where the point of force is being applied, is certainly an area where an amount of cushioning is also working against the hard / full contact force being exerted to its worst effect.

If the Base the Albums are laying on is perfectly flat then the lower Album should not be exposed to being compressed onto the uneven surface in the area of the Grooves.

As an optimist, I sense the Paper Sleeves may have been exposed to a accelerated deterioration as a result of the environments impact at the storage location. Proper Cleaning Methods will firstly correct any earlier used cleaning methods failings, as well as deal with contaminants from inner Paper Sleeves deterioration being bedded into the groove as well. 

I keep the original Paper Sleeve stored in the Album Cover, but use Anti Static Sleeves to insert the Vinyl into  following the PAVCR Manual Cleaning Method.

Ring Damage to Album Covers is quite likely.

Warping is also a risk. 

The question is when you do get to have hands on the Vinyl LP's once more, are the Storage methods to change, is the new configuration to be that the Albums are to be flipped to the Vertical for the period of storage until you can get to using them regularly ?!!!

Do not overlook that this Album Collection is very likely to be worth a reasonable sum of monies, it can also contain an Album or Two that are much appreciated in value as well. 

The causal formula for vinyl deformity is (Heat > 70 degrees F+ Uneven pressure across a recrd’s surface) / Time.

IOW: The vinyl substrate on which records are pressed softens in direct proportion to exposure to temperatures >70º Fahrenheit. The duration of their exposure is inversely proportional to the temperature elevation that softens vinyl to the same extent.

Record warping is a process that begins when heat softens the vinyl enough to deform during the simultaneous application of uneven pressure across a record’s surface. This uneven pressure occurs when records lean to one side. The higher the temperature, and/or the greater the uneven pressure, the less time it takes a deformity to develop.

The closer one edge of a record’s proximity to a home heating source, the greater the tendency for an isolated edge deformity to develop. Edge warps cause phonograph styli to skip or repeat playback of a record’s outer grooves. An edge warp that extends far enough toward the record’s center can render the introductory portions of the recorded music unplayable. Severe edge warps under the influence of modern anti-skating mechanisms can toss a playback off the edge of the record. Most edge warps are irreparable.

“Dish” deformities develop when an entire record is exposed to heat while the angles at which they lean are great enough to form pressure voids over a substantial portion of a record’s large midsection.

Dish warps decouple a record from the turntable platter when they’re played. This phenomenon allows the record’s inherent resonance to color the sound listeners hear—differing in intensity with each record rotation. This, in turn, has a deleterious effect on the fidelity that leads music lovers to choose vinyl records because of their extraordinarily high fidelity to the music’s source. The good news is that dish warps are repairable, as described by Sumiko

Either deformity becomes set when a deformed record cools. Repeated heating/cooling cycles “ratchet” up the warp’s severity over time until listeners finally notice it. The bad news is that in most cases, the process is so insidious that the process goes unnoticed until it’s too late to prevent it.

The good news for you, SOIX is that per your description, your record collection hasn’t been subjected to temperatures >70 degrees F while they’ve been stored as you’ve described. So unless they were subjected to temperatures > 70 degrees F at the same time they were exposed to uneven surface pressures before you began storing them as you’ve described, I can assure you that your valuable and sometimes irreplaceable records are not warped.

Look for Diamond Record Guardian, LLC to introduce its failsafe warp prevention system at the beginning of July.

Where do you get your “rules of warping”?

@soix The Post from @recordguardian a very appropriate name, has made it clear what is a ambient environment condition that can cause a warp to occur.

When hands on with the LP’s, this is one more consideration to be checked for and avoided, for this condition to be created in close proximity to the LP’s.

I don’t think there is an LP owner from their heyday of usage that has not had a LP warp from leaving an Album local to an external window that receives Sunshine.

I may have even been expressive of a wicked nature, where at a certain time, exposed a Sibling Brothers Album or Two to such a condition 👹

@lewm

You asked, "Where do you get your “rules of warping”?"

Thank you for asking.

I got those rules from verified facts and sound logic. The verified facts were gathered from extensive research I engaged in order to understand my 55 years of anecdtotal experience with warps in my own records added to the experiences of other record collectors posted on the internet.

The sound logic cmes from my undeclared minor in formal logic when I earned my bachelors degree in business administration, passing all of my science and math courses with nary an error.

Assuming you have your own "rules for warping", how do they differ from mine?

Thank you.
