Abstract
An electrical drive motor system for a camera having a read head for reading magnetically encoded data from a filmstrip during a reel-to-reel transport of the film, includes a mechanism for storing energy in a mechanical motor spring. The energy stored in the spring is used to temporarily continue or complete the advance of the film with the electric motor shut off, to allow the read head to operate without electromagnetic interference from the electric motor.
