Document Type and Number:
Japanese Patent JP3397223
Kind Code:
B2
Abstract:
PURPOSE: To effectively use a magnetic recording layer at the tip part of a photographic film having the magnetic recording layer by writing down the information in the magnetic recording layer at the time of winding up the film.
CONSTITUTION: At the time writing is carried out in a magnetic recording layer of a photographic film, the film in a film cartridge is wound up to the final photographed frame on a winding up reel installed outside (S12). Continuously, winding of the film on the film cartridge is started (S14) and at the same time a perforation formed in each photographed frame is detected (S16) and based on the position, the information regarding each photographed frame is written down in a prescribed region (S18).
