How did early mechanical recorders, used before electrical sensing, typically create a physical record of movement?
Answer
By using stylus-on-soot or inked-drum methods
Early mechanical recorders established a physical trace of movement, often relying on rudimentary methods such as a stylus drawing on a surface coated with soot or using ink deposited onto a moving drum.
