45 revolutions per minute. This denotes the speed at which a turntable should be spinning in order to play a 45 record disc. when referring to records such as 45 RPM the RPM means:
R= Rotations
P= Per
M= Minute these refer to the speed at which the disc was recorded and will be turned while being played on a turntable
other speeds were also 78RPM (very old and very hard to find anymore) and 33 RPM which was the other common speed when records were the popular the 45's were about 8" in diameter and the 33's were about 11"or 12" in diameter. Hope this little bit of music history answers your question and fills your mind
The above answer is pretty much on the money....I'll add my two cents worth........
I believe that RPM stands for REVOLUTIONS PER MINUTE. The old fashion record PLAYERS that played the "78's" were called phonographs and had only one speed- 78 RPM's. The more recent record PLAYERS usually had two speeds- 45 (RPM) and
33 1/3 (RPM). They could play the smaller vinyl records (or disks)- the "45's"- AND the larger vinyl records called "ALBUMS" or "LP's" (short for "long playing") at 33 1/3 RPM. The 45's had only one song on each side, while the LP's had multiple songs on each side. Now, everything is on a CD, but many times they still refer to them as "albums". REAL VINYL records and albums are not sold anymore, unless you go to a specialty record store that carries "antiques"!! <<<adr>>>
there are several speeds for vinyl records, but for common formats it is 33 rpm, 45 rpm, 78 rpm and actually 33 1/3 rpm. that's what they were called 45's because they made 45 revolutions or rounds but it's actually revolutions per minute.
A seven inch disc played at 45 RPM (revolutions per minute) on a turntable; also known as a "single".
On a music score it stands for "left hand".

I've seen it called a 45 RPM Adapter.
This was called an 45 RPM adapter or spindle adapter, since it allowed you to play 45-RPM records on a player with a regular long-play spindle.

A 45 rpm record typically weighs around 7-9 ounces.
There are many valuable 45 rpm records, some of them worth thousands of dollars. Some of the more valuable 45 rpm records are by: Bob Dylan, The Beatles, and Elvis Presley.
L.P. stands for Long Player, a 12" vinyl record with multiple tracks played at turntable speed of 33 RPM
The 45 RPM records or vinyls sound as they were intended to sound when played at 45 revolutions per minute (at the 45 setting on a record player) while the 33 RPM records sound right at the 33 revolutions per minute speed. Then, there is the issue of size. Records that are 33 RPM are larger in diameter than 45's. Also 33's can hold more songs than 45's do. Usually, 45's have only one song on a side and were used as demo records for radio stations (yes, radio stations used to play music on records before they went to tapes and now to digital music on computers) and for releasing "singles" so that people could listen to a new band without having to pay for a whole album. 45 RPM records or vinyls are recorded at 45 revolutions per minute and are consequently played back at the same speed to achieve exact replication of the original recording. Subsequently, 33 1/3 RPMs are recorded at that speed, and played back at that speed to hear the audio as it was recorded. Generally 45s are recorded on smaller 7" disks, whereas 33 1/3s are recorded on larger, full sized 12" disks. This is not always the case, as some 12" records are recorded at 45 RPM for higher, or audiophile, sound quality.
They typically drag because that's how they make sound. If it didn't dray there would be no music. If you mean that it sounds slow, that is because as stated above, it is part of the process. Better turntables have a strobe to adjust the timing, or speed of the rotation to keep it at 33 rpm or 45 rpm or 78 rpm. Which brings me to the next part of the answer. Make sure that the speed of the turntable matches the speed of the recording. Playing a 45 rpm record at 33 rpm will sound very slow and dragging. Most record players and turntables have a selector for 33 and 45 rpm. 78rpm records use a different needle, and not all players will play these older format records.
