I think you knew all along that those numbers were centimetres. Anyway it is more proof that the records are, always were, and always will be fully metric.
Why are you trying to insist that centimetres are not UK measures? They are as UK as the Queen. Inches are the units that are not UK. They were brought tot he UK by the Romans, thus they are foreign. It doesn't matter how some instruction book described a CD. It is 120 mm diameter no matter how you describe it. Just like vinly records have always been metric no matter how much some tried to corrupt the truth. Is your frustration against metric so strong that you have to accept inch error in order to get the warm and fuzzies? When are you going to measure your records and CDs and post the results here for all to see?

The few undamaged cells I have left 'up there' reminded me that when I was in my early teens I had a turntable built by Sharp which also had those numbers. Believe it or not I did not add 2 and 2 at the time - so to speak - and I did not realise the significance of those figures!!! Yes - I'd agree that it has little to do with vinyl and history etc - more to do with far eastern goods being metric. On my documents I noted an odd thing - with the CD player (I have very few CD's) the English section of the european instructions shows the CD format in UK measures with cm in brackets. That's not the oddest thing - the French section has metric and then inches (pouce) in brackets - bear in mind the CD player is european and wont be destined for canada. Other european languages only have metric. FYI - and following your lead about my hobby - My Linn has a belt driven motor - plays 33.3 only (well you can force a 45 spindle - but I hate doing that) and the unipivot naim aro arm is totally manual! I use a Linn akiva cartridge (MC) which goes via a Tom Evans phono stage to the pre-power amp pair (naim) through Dynaudio speakers via naim cabling. The tunrtable has a Naim Armageddon power supply and a dedicated unswitched power socket. The sound it makes is gorgeous! ________________________________ From: w...@wfpconsulting.com To: usma@colostate.edu Subject: [USMA:44446] RE: Records Date: Mon, 6 Apr 2009 11:21:52 -0700 Steve: I have a 1980s-era Kenwood KD5070, which has a resin-concrete base (anti-resonance). It's direct-drive "full-automatic" single-play. I bought it (new) here in California. Its illuminated stroboscope has tracks for both 33-1/3 and 45 revolutions per minute at both 50 Hz and 60 Hz. It has a knob for setting the size of the record being played. There are four settings for the knob: 30, 25, 17, and Manual. That neither proves nor disproves your historical assertion regarding the oldest records (which go back to long before the introduction of long-play vinyl). It does show that Matsushita (the real name behind Kenmore and, at one time, TRIO) chose SI (and only SI) for the turntables it was selling internationally in the 1980s. In the Instruction Manual, specifications are given in metric units, with parenthetical US customary units in some (but not all) cases. Incidentally, my wife and I were revisiting our ABBA LPs last night -- still in perfect condition. We also have quite a bit of our classical collection (including all of Beethoven's Symphonies) on Deutsche Grammophon LPs (although we now have vastly more on 120 mm CDs). Occasionally, I'll still play some of my Timeline Swing Era collection (also in perfect condition). As a final note, one of our two black-and-white cats sometimes settles down on the hinged dust cover, even when a record is playing.

Besides the fact that 12" (10" and 7") were around since the UK/US even knew of metric they are still imperial based today. What you (JPS) don't realise (although in reality you prob do) is the shrinkage after the first 14" inches are pressed. If it helps high quality records are usually expressed in grammes (eg 130 gramme vinyl). You may see a difference here - I purposefully point out metric usage in vinyl record production whereas our returning poster cannot debate the idea that records can possibly be anything but metric and searches google for a rare mention of metric. From Germany. As it happens I'm an audiophile and analog is my big hobby - I wonder if anyone out there shares my passion and has a Linn Sondek LP12 deck? :-D ________________________________ Date: Sat, 4 Apr 2009 06:53:56 -0700 From: jeremiahmacgre...@rocketmail.com Subject: [USMA:44328] RE: Records To: usma@colostate.edu CC: usma@colostate.edu Brian, My point is that the records never were the dimensions stated in inches. Go measure them, just don't look at them. The 7 and 10 inch records were originally designed with metric dimensions in mind as 175 and 250 mm and those dimensions continued on even when the name was changed. The LPs made by American companies are 302 mm (not 305 mm) and the ones by foreign companies are a true 300 mm. Even if it was conceived in inches it wasn't 12 (305 mm). It goes to show you that those who claim to know inches don't really recognize them when they are wrong and refuse to measure them for fear of having to admit the truth that they are not an imperial conceived product. I believe they would fall into the category of hidden metric. The so-called 3.5 inch floppy disk fell into the same category. It was a true metric product of 90 x 94 x 3.3 mm.

In my opinion this is one of those situations where the inch term can still be used even if the US was totally metric. Nothing wrong with calling an album a 12 inch. (Technically the 33 is a 33 1/2 rpm album....) Speaking of that, the Ice-T song "I'm your pusher" had a little dialogue in which a supposed drug user is asking Ict-T for some drugs and Ice-T responds, "I can hook you up with a twelve inch." I do agree with you Jerry that mostly in the US we say 45s and LPs vs the size. However, there are many instances (usually corner cases) where inches were used. I remember back in the day, during my hardcore punk listening days, bands would "cut a 7 inch". At the same time, you'd get special remixes usually on a "12 inch". I still have a handful of 7 inch records cut by small indie bands....and also a full 12" extended mix of Michael Jackson's Billie Jean. ......and lots of times when these extended mixes would be released on CDs, they'd be refered to as 12" extended mix. I have quite a few Depeche Mode special issues with these references, although to be fair, mostly they were reissues containing UK dance hall remixes or were UK imports to begin with. With regards to your measurements though, lots of my vinyl is of different construction. Some are very thick, heavy, and brittle. Others are thin, floppy and seem to be able to be bent strongly without cracking. Looking at and holding these albums, they have slightly different lip edges which could easily account for 3mm. I'd be curious to take a larger measurement sampling. But considering the LP (the 33 1/2 rpm album, 12 inch) was designed by an American company, I don't doubt it was designed to inches. -------- Original Message -------- Subject: [USMA:44320] Records From: Jeremiah MacGregor <jeremiahmacgre...@rocketmail.com> Date: Fri, April 03, 2009 8:38 pm To: "U.S. Metric Association" <usma@colostate.edu> It seems the 45 min^-1 record is 60 years old. http://news.bbc.co.uk/2/shared/spl/hi/picture_gallery/08/business_the_seven_inch_single/html/1.stm This is one of those remnants that extremists get excited over because the record mentioned is called by an inch name, even though it is incorrect. In the US we never called records by their inch size. We always called them by their speed. We had the 45 min^-1 singles, 33-1/3 long playing and the older 78 min^-1. Everyone knows them simply as 45s, 33s and 78s. Never anthing else. Yet extremists falsely claim these to be inch based because they were falsely given inch names. I happen to have a sample of all three record types and I can honestly state that none are to the measurements the extremists drool over. My 45s are 175 mm. 7 inches is 178 mm. Thus the records are 3 mm shorter then their inch name claim. My 33s are 302 mm. 12 inches is 305 mm.. Thus the records are 3 mm shorter then their inch name claim. My 78s are 250 mm. 10 inches is 254 mm. Thus the records are 4 mm shorter then their inch name claim. I believe that outside the US 33s are 300 mm exactly. Some of you on this list who do not come from the US may be able to check their record collection and verify the diameters. The 17.5 cm disc was originally designed by Emile Berliner of Germany and he chose the metric size as standard and the inch sizes were the closes the English could come up with, but even with inch names they never changed the sizes Berliner chose to the rounded inch sizes they named them. Berliner arranged for the first gramophones to be made in Europe during the trip to Germany 1889-90. According to Raymond Wile, "It was in Germany that the first commercial beginnings of the gramophone occurred - presumably in July 1890. The toy makers Kammer and Reinhardt in Waltershausen (Thuringia) began to market small hand-propelled gramophones and a talking-doll. For the doll, a small 8 centimeter disc was prepared, and for the regular machine a 12.5 centimeter disc. The records were available in three substances during the period they were marketed. Without adequate documentation it is impossible to determine if the copies made in hard rubber or celluloid were contemporaneous, or which substances had precedence. For an additional price, zinc discs also were available. The records were produced by two companies, one known solely by the initials GFKC, the other was the Rhenische Gummi und Celluloid Fabrik Werkes of Necharan, Mannheim. The machines and records also were imported into England, notably by J. Lewis Young, but were available for only a few years in both countries" (Wile 1990 p. 16). As a result, Berliner's efforts led to the establishment of Deutsche Grammophon Gesellschaft (DGG, later to become PolyGram). http://history.sandiego..edu/gen/recording/berliner.html Thus despite the corrupted names, vinly records are a true metric invention.
