Phonograph Cylinder - Advantages of Cylinders

Advantages of Cylinders

The cylinder system had certain advantages. As noted, wax cylinders could be used for home recordings, and "indestructible" types could be played over and over many more times than the disc. Cylinders usually rotated twice as fast as contemporary discs, but the linear velocity was comparable to the innermost grooves of the disc. In theory, this would provide generally poorer audio fidelity. Furthermore, since constant angular velocity translates into constant linear velocity (the radius of the helical track is constant), cylinders were also free from inner groove problems suffered by disc recordings. Around 1900, cylinders were, on average, indeed of notably higher audio quality than contemporary discs, but as disc makers improved their technology by 1910 the fidelity differences between better discs and cylinders became minimal.

Cylinder phonographs generally used a worm gear to move the stylus in synchronization with the grooves of the recording, whereas most disc machines relied on the grooves to pull the stylus along. This resulted in cylinder records played a number of times having less degradation than discs, but this added mechanism made cylinder machines more expensive.
