Definição do conceito
[ENG] rotation (phonograph cylinder): The length of sound recordings on a cylinder depend on the dimensions of the cylinder, numbers of grooves per inch and rotations per minute (rpm). Soft wax cylinders (cylinders with 100 grooves per inch) ran approximately 2 to 2.5 minutes of playing time. "Longer Play" cylinders with 200 grooves per inch ran twice as long, up to 4.5 minutes. Cylinders also have different rotations per minute, depending on the manufacturer and advances in technology: e.g. 120 rpm, 144 rpm, or 160 rpm. | Many manufacturers produced cylinders in its heyday, but the only substantial difference in the recording or playback of different cylinders corresponds to the diameter of the cylinder, which requires a corresponding size armature to hold it. Cylinders were recorded acoustically (also known as mechanical recording). Acoustic recording is defined as sound waves affecting a diaphragm attached to a stylus, which will impress a sound track corresponding to the sound waves onto a recording medium. | SOURCE: https://www.conservation-wiki.com/wiki/Cylinders

[ENG] Recordings on cylinders were made at a variety of speeds, between 120 and 160 revolutions per minute (rpm) depending on when they were recorded, what company recorded them, or what machine was used to record a cylinder at home. | (BRYLAWSKI, Sam et al.) https://www.clir.org/pubs/reports/pub164/

[SPA] rotación (cilindro de fonógrafo): Rotación de cilindro o platina - El motor que impulsa el cilindro o la placa consiste en un resorte similar en mayor dimensión al de un reloj, péndulo o reloj, de un juguete mecánico o de una caja de música, formado por una larga cinta de acero forzado en una carcasa cilíndrica. . El operador acciona una manivela durante las pocas vueltas necesarias, hasta una cierta resistencia correspondiente al bobinado completo máximo. El ajuste en rotación o el tope se realiza inclinando una palanca provista de una orejeta de goma que mantiene o libera la placa por fricción. | FUENTE: https://es.frwiki.wiki/wiki/Phonographe#Rotation_du_cylindre_ou_du_plateau
