record players and how they work

So recently, record players have been making a resurgence. While there's no denying that they're pretty cool, and sound way better than a cd or mp3 (if you even care about that) they work in a pretty cool way. Record players as we know them now, work by spinning a record on a turntable, that is usually belt driven to spin a record at a given speed, most commonly either 33.5 rpm or 45 rpm. record players have a needle that runs through the grooves of the record that picks up vibrations which are sent through the needle, into wires in the are that are then sent through a coil in a magnetic field which then converts it into an electrical signal that is sent through an amplifier, and finally the speakers, producing the sound that you hear. there are a lot of factors, however, that can contribute to how a record plays. for example, if there is a scratch in the record it could skip through the song. also if the grooves in the record aren't deep enough, the record could skip over the grooves without a scratch even being present just from the oscillation of the needle. Some of these issues can be fixed with features on the record player, such as anti-skate, and anti-skip features, which changes the tension of the arm on the record which will generally help the record stay in the grooves better, and possibly even play through  a scratch with only minor hiccups where the scratch is present rather than skip through the entire song.
