Why did Emile Berliner focus on the flat, rotating disc for the gramophone?

Answer

Discs could be mass-produced cheaply and easily

Emile Berliner introduced the gramophone in 1887, moving away from cylinders toward the flat, rotating disc. The primary motivation for this shift was manufacturing economics. Unlike cylinders, which required individual, time-consuming duplication, discs could be mass-produced efficiently using a stamping process similar to manufacturing metal items. This made recorded sound accessible and affordable for the general public, establishing the foundation of the modern record industry.
