Analog recording technology [part 2]

After 1st part : 

And that something is an analog of the original sound waves, improvements in sound technology were for many years wax cylinders became shellac discs & shellac became vinyl magnetic recording wire allowed for a reusable electronic recording medium.

This was improved into Magnetic Tape allowing for a high-fidelity versatile recording medium enabling multitrack recording and editing and to improve on the noise of magnetic tape different particle formulations were developed and noise reduction technology was finally mature.
                                                        

But we were still just taking some signal from a microphone then slapping it basically as is on to some sort of physical medium and that Medium was never perfect, poorly made tape would cause signal dropouts, discs would be plagued by dust and scratches and would slowly we're down with each play because the analog medium contained the sound in its physical properties. 

It was inherently prone to wear damage and Distortion which of course would wear down damage or distort the sound recording itself !
