3.1 CONCEPT
The Aaton magazine has been designed to be instantly installed or
removed, and to be loaded quickly. In order to have a more compact
magazine, both cores (feed and take-up) shift together during fil-
ming.
The magazine is driven magnetically from two intermediate drives
connected to the camera motors; two magnetic wheels on the inner
side of the camera body couple with two similar wheels on the
throat of the magazine to transport the film. A magnetic drive sys-
tem decreases noise and power consumption, and prevents mechani-
cal stress during mis-loads.
The magazine handles up to 400 ft (122m) loads of 35mm film
stock. 400 ft of film is a little more than 4 running minutes at 24
fps
3.2 PRESSURE PLATE SYSTEM
The magazine features two pressure plates which are located at the front
of the magazine’s nose. When the loaded magazine is attached to the
camera, these pressure plates provide the precise stabilization of the film
during exposure and transport.
3.2.1 The Gate Plate
The long plate, called the gate plate, is positioned at the camera’s
gate. Its main function is to stabilize the film as the claw engages the
film perf between exposures. Proper tension and functioning of the
gate plate contribute to reliable transport and quiet operation.
3.2.2 The Picture Plate
The striped pressure plate, called the picture plate, is positioned at
the camera’s aperture opening and is designed to hold the film stea-
dy at the point of exposure. Proper setting and functioning of the
picture plate assures the precise focus of each image.
