The average tangential needle speed relative to the disc surface is approximately one mile per hour according to the article. Averging over a radius from 15 to 7 cm we get 1.382300768 km/h or 0.383972435 m/s, which is about 1 mph. Jimp 06:38, 2 July 2014 (UTC)
Someone here needs a lesson in doing calculations and giving results using significant figures. 1.38 km/h or 380 mm/s, neither of which is close to 1 mi/h or 447 mm/s. — Preceding unsigned comment added by Ametrica (talk • contribs) 12:02, 9 September 2016 (UTC)
What is the essential difference between a LP record and an album? If there isn't one, then the articles should be merged. If there is one, then that should be described. What, for Wikipedia purposes, is the distinction between LP record and Gramophone record? I'm wondering if LP record is stuck between describing album and Gramophone record, and if so, should the article be refocused, or should it be merged? SilkTork ✔Tea time 09:12, 4 December 2015 (UTC)
An album can be made up of one LP record, a pair of them (a Double Album), three (a Triple Album), etc., or as was said above, could be music released on other formats such as CD or cassette. An LP record is just that. One Long-Playing record. A single lump of plastic. A Gramophone record is not necessarily an LP. A gramophone record is playable on a gramophone, but that doesn't carry with it the long-playing aspect. 45RPM and 78RPM records are both gramophone records, but are of short duration, therefore not LPs Musicfan1353 (talk) 16:51, 1 February 2016 (UTC)
Does all of the above get solved by merely changing the first sentence of the introduction from "This article is about vinyl or gramophone records. " to "This article is about the long-playing (LP) vinyl record, a type of gramophone record. " ??? Musicfan1353 (talk) 17:00, 1 February 2016 (UTC)
it might be time to update the last sentences of this section, specifically
in 2016, vinyl dominates existing bricks and mortar stores, which are themselves a niche market ... whether or not this is a fad is debatable but the record companies and stores are clearly exploiting the demand while it exists ... there are plenty of articles on the "vinyl revival" in the mainstream press that could be used as citations, including info on new and old pressing plants ... J Edward Malone (talk) 19:42, 15 June 2016 (UTC)
This. Ought be difficult to prove one way or the other, but I would suspect the record referred to in this simile is in fact a 78, not a vinyl record. Vinyl records do not very easily break, although it is easy to scratch one. Shellac records are rather easy to crack or break, and if you have a record that remains on one piece but has a crack, it will skip. I guess you could call a severely scratched vinyl as being "broken", as sometimes "broken" is used as a synonym for "defective", but I remember this saying from as far back as the early 1959s, when 78s were still quite common while vinyl was more of a niche market.

I do believe that Cooks binaural records belong in this article as they are the first commercially available two channel recordings on disk but some of the details are inaccurate.
Here's the text: "Emory Cook's 1952 idea of using two tracks, and a system using vertical modulation (harking back to Edison's 1877 experiments) for one channel and (then-universal) horizontal for the other".
I believe that there are two issues here (although perhaps only one is inaccurate).
The two channels on Cook's binaural disks are recorded with different equalizations but both are horizontal. A Cook binaural tonearm (such as that manufactured by Livingston) simply required two standard cartridges. For more detail see the discussion in the Cook Records entry.
Also, Edison's disks were successfully marketed for a number of years (1912-1929) and were cut vertically (hill and dale) so I don't know that characterizing the method as harking back to his experiments gives the right impression (although this is, of course, accurate).
I'd have changed this but I thought that the original author may want to investigate and change.

Nice to know someone else owns some of these. I have a few myself. I have a thing for obsolete technology so I have collected a bit of Cook-binaural equipment over the years and have interacted with others about this. imagine that I'd have heard of another format if it existed. This is especially the case since it would suggest a different style tonearm and I have spent an embarrassing amount of time obsessing about tonearms. As a consequence, I am fairly certain that there are no disks quite like those described. It is certainly the case that there are no tonearms that have ever been manufactured for playback (which, oddly enough, I'll admit doesn't mean that the disks were never made). I wonder if this description is not a kind of permutation of the description of standard Westrex-style stereo, which essentially combines the vertical and lateral (as noted later in the paragraph). — Preceding unsigned comment added by RichardBeckwith (talk • contribs) 16:39, 26 January 2017 (UTC)

I know it might vary somewhat, but there's presumably a certain set range that the run-out area and lock groove occupy in order to maximise play time whilst remaining compatible with automatic systems? And it's probably not changed since the days of the macrogroove 78, so that people can still play their shellac on a modern turntable equipped with a suitably robust needle... Do we know what it is? I guess at about 10cm or four inches before but apparently that's wrong. It's a useful thing to know both for calculating linear media speed at the end of a disc (from which we can estimate frequency range for a particular playback stylus and/or cutting head, both at the start and end of a side), and how wide a recording band is provided on a typical 7, 10 and 12 inch disc (and so how many grooves of a particular width will fit in that space, and thus the theoretical maximum playing time)... It's not given anywhere in this article, nor in the general "vinyl record" one. 46.208.118.253 (talk) 10:28, 9 April 2018 (UTC)
This article needs sections added on The Audiophile Companies such as Mobile Fidelity who produce extremely high qualilty products.
This and other related sections need to be updated and added to reflect the fact that Vinyl never stopped being produced and now, as we near the end of the Physical CD format in favor of streaming, that Vinyl sales have been skyrocketing in the last few years. New Products are being announced at CES and the value of Vintage Record Equipment is on the increase — Preceding unsigned comment added by Imagineer2018 (talk • contribs) 01:44, 8 February 2019 (UTC)

I actually own this album. It's not a single LP with 90 minutes of music. It's 2 LPs. I don't think that this is a good example for an extended play LP. Tdknox (talk) 20:52, 30 August 2019 (UTC)
I am moving the following uncited material here until it can be properly supported with inline citations of reliable, secondary sources, per WP:V, WP:NOR, WP:CS, WP:NOR, WP:IRS, WP:PSTS, et al. This diff shows where it was in the article. Nightscream (talk) 14:42, 23 July 2022 (UTC)

While it’s nice to have some logo visuals, File:LPlogo.svg lacks both source and author information, and above that, any authority to provide a logo for this type of medium. I suggest it being removed, or anyone could provide a phantasy version of “a logo for LP record”. -- WA1TF0R䷟ 09:35, 30 July 2022 (UTC)
In theory, quantization noise for 16 bit audio CDs is about -100dbB. That isn't zero. Practically, it is below just about every other noise around, in just about ever environment. Maybe except for an anechoic lab. Gah4 (talk) 09:40, 1 July 2023 (UTC)
There are 2 images referencing "Neumann lathe." Yet there is nothing in the article referencing the subject. More information is needed. 76.88.55.202 (talk) 03:19, 11 August 2023 (UTC)
I noticed this article does not cite a patent or a paper showing the original specs (e.g. weight, groove size...) of the long play vinyl record. Do they exist?-- Carnby (talk) 22:10, 17 March 2024 (UTC)
So a bad thing about this article I see is that, in addition to talking about the original LP from Columbia and the history behind it etc, it also contains numerous contemporary info that isn't necessarily specific to the LP and these are basically already covered in phonograph record. Since the phonograph record article talks generally about all record formats, this article needs to focus specifically on LP when it was still something distinctive.
It's really confusing. I imagine a young kid reading this who wants to know about records will just end up confused about how there's this LP and a phonograph record without a proper explanation for them (and the fact the term "LP" is still used generically). I am going to make edits to this article to make it more clearer at the top and maybe remove some of the very recent stuff that are already in phonograph record.
