How many grooves does a vinyl album have?
Two-Channel Stereo (Part 10: Phono Cartridge) It’s an old, silly riddle: how many grooves on a record? Of course, the answer is just one on each side—but that groove is usually about 1,500 feet long, or about 1/3 of a mile.
How far apart are the grooves on a record?
A record’s groove – and there is generally just one that spirals gently to the centre of the disc – is tiny, usually around 0.04-0.08mm wide (depending on the level of the signal). If you were to unravel it, the groove on a 12-inch LP would extend to a length of about 500 metres.
What are the grooves on a vinyl record called?

How do the grooves on a record make sound?
A stylus on the record player moves through the grooves imprinted on the disc and “reads” them. This reading generates an electric signal which is transferred to an amplifier. The amplifier ultimately conducts the signal to the speakers, from where it will come out as sound.
How do record grooves work?
As the record turns, the stylus falls into the tiny cut grooves, causing it to vibrate. As the stylus vibrates, so does the cartridge that it’s attached to. The cartridge is a transducer, this creates an electrical current that changes depending on the stylus’ vibrations.
Why do vinyls sound better?

Do CDs have grooves?
CDs are easily scratched, and should never be cleaned with just any cloth. CDs should be cleaned radially: not along the grooves, but at right angles to the direction of the grooves. If a smear, however small, should remain on the CD, running along the direction of the grooves, much information would be lost.

What is a 33 rpm record made of?
They are typically made of a shellac compound (as in furniture finish!), and have the consistency of a china plate, so they are very thick and heavy and break easily. The 33, a.k.a. the “LP” (Long Playing record) or “album”, pictured above at left, was invented in 1948.
What are microgrooves on a vinyl record?
In 1948 Columbia Records introduced “long players,” or more commonly referred to as an “LP.” LPs were to fulfill the need of longer playtimes by spinning the record at a slower 33 RPM. Reducing the speed so drastically was possible through “microgrooves.” Microgrooves are just a smaller groove within the vinyl record.
What is 33 1/3 rpm?
This new speed was 33 1/3 rpm, adopted for other records in the late 1940s when Columbia introduced its first vinyl, long-play discs with microgrooves, giving a play time of about 30 minutes on each side.
