How many grooves on a record

I listen to opera, choral music, classical, jazz, blues, rock and pop, bluegrass—the connection between them seems to be emphasis on voice and acoustic over electric or highly produced recordings. When I began to ask about the Dynavector DV20x20 , people started telling me that this was the right cartridge for me, especially if I intended to upgrade the turntable in the future.

So l started listening. Or, first, I paid a local audio dealer to mount to cartridge properly—this is not an easy thing to do properly—and then I started listening to the DV20x20 on my Rotel RB turntable. Now, I hoped to hear a substantial improvement by replacing the Shure V15vx phono cartridge with the Dynavector DV20x Sure enough, I heard what I hoped to hear—immediately!

The low strings were even more clearly defined, distinct from one another, with greater body, more luxurious fluidity, and a greater sense of presence, and, looking for a word here…snap! Moving to the higher strings, they gained a sense of reality, smoothness, and again, presence. The winds can tend to be a bit screechy on this recording, but they were nicely managed by this cartridge.

On classical recordings, I find the overall presence most appealing, closely followed by the punch and sweep of the more exciting passages, and increased refinement of solo violins, female voice, clarinets, oboes, and flutes.

I pay more attention to the music! In short, this tiny component—a phono cartridge half the size of my pinky—is providing a whole lot of enjoyment. With a VPI Prime turntable. This article is part of a series. There are some fair reasons for this. The width of a groove itself depends on peculiarities of the recording, such as the volume of the sound and the noise compression at play. How close together grooves can be depends on the quality of the material.

Let the recording staff figure that out. Taking the playable outside of a record to be That seems to be about the right size if I actually hold up and look at a record, although I would probably have rounded that to around three and a half inches. And in something I thought would never happen, I ran across a Yahoo!

Canada Answers; perhaps that makes the difference. Canadian answerer billrussell42 claimed the groove spacing was variable but about micrometers, which works out to grooves per inch. Answer page. For the curious, billrussell42 also says the spacing on a CD is 1. I have some authorities who may well be qualified endorsing the answer I reasoned out, but part of why I find them believable is that they do agree with my answer.

But my reasoning is pretty straightforward and the assumptions which go into it seem easy to check. Those disputing my reasons are welcome to say so, and I will respond with an essay on what the Muzak corporation did to help win World War II.

I was born years to the day after Johnny Appleseed. The differences between us do not end there. View all posts by Joseph Nebus. Your second approach is how I answered the worked through the trick question as a failed attempt at extra credit on a math exam in high school. I did not get any credit, which I think is really nasty.

I believe we were given the duration of the record as one of the parameters. Like Like. In my case I started out with too hard a problem by figuring to use more tools than were actually needed, and had to work through that before simplifying it to where you started. And, yeah, putting a trick question like that on as extra credit and not crediting people who do the real work that gets at what people not putting it as a trick question is rotten.

Different records are pressed with different groove spacings depending on material and mastering and so on. So it depends a lot on the record. Our role within the project is therefore to measure and characterize the plastics and to validate the sound quality of the new type of vinyl. The groove shape determines how the needle goes over the plastic and how the sound sounds.

To determine whether the sound is also good, this is tested and validated by the Applied Physics students. However, testing and validating is easier said than done. The accompanying album covers of 78 vinyl records are often worth as much or more than the actual record discs. But reading their FAQs, it does not appear they will ship those old records back to you.

Vinyl records also come in three standard diameters: 7-inch, inch and inch. These discs can only record data once and then the data becomes permanent on the disc. The data on a CD-RW disc can be erased and recorded over numerous times. How many grooves are in a 33 rpm record? How many grooves does a vinyl record have? How many grooves are there on a CD?
