A sound-on slide projector including a scanning device for magnetically recording or reproducing sound on a slide. The device traces a spiral locus along the magnetically coated frame of the slide film without using any guiding means. The projector also has detecting means for sensing positions of the magnetic head. The detecting means energizes means to reset the magnetic head, which cooperates with magnetic head detaching means disposed between the slide frame and the scanning device. Guard switch means are also included in order to prevent operation of an automatic slide frame changer when the scanning device is operating.
A display apparatus (18) capable of sequentially displaying a plurality of annotated image prints (36), each image print having encoded audio data (54) made integral to its back surface (46), thereby providing a convenient way to both display image prints and play back audio data associated with image prints. In one aspect, the display apparatus (18) also records audio data for a plurality of image prints and provides a handwritten means to electronically associate a particular image print with its respective audio recording. In other aspects, the display apparatus (18) also includes means for integrating encoded data (54) with the image prints and recording, storing and playing back data corresponding to a portfolio of image prints. There is also a method of capturing images and corresponding audio messages, integrating the audio messages with the back surfaces (46) of image prints made from the images, and displaying the image prints while playing back the corresponding audio messages.
