Abstract

A sheet of exposed and developed instant-camera film is discharged from an instant camera and then inserted by the user into a film-holding structure on the back of the camera which very accurately positions the film sheet, such that upon removal and reinsertion of the film sheet into the holding structure the film sheet will always assume a predetermined position. The camera is provided with a multihead magnetic head unit mounted for reciprocating motion along a magnetic strip or coating provided at a marginal portion of the inserted film sheet. During first-direction travel of the head unit, one head records, and during second-direction travel of the head unit a different and differently located head records onto a further segment of the magnetic strip. After recording, the recorded information, e.g., spoken words identifying the subject just photographed, can be reproduced, and if desired erased.
