Abstract: An image-audio print has either a single image or a set of images on a first side and an accessible audio data storage means preferably on its backside. The accessible audio data storage means contains an audio data segment associated with the image on single image prints and a set of audio data segments, one for each image on multi-image prints, for example, index prints. A player receives and locates the image-audio print with the accessible audio data storage means accurately positioned in electrical contact with the player apparatus. The player apparatus can play an audio data segment associated with the print from a single image print or by appropriate interaction with the user who selects a audio data segment associated with the selected image on multi-image prints. Preferably, a touchscreen is used to select the image for which the audio is to be played. The player also can record audio into the accessible audio data storage means and copy audio from one print to another.

Abstract: A rigid camera with a film holder independently rotatable about a horizontal axis and a vertical axis. The film holder rotates synchronously with the focusing plate of the viewfinder. The focusing plate rotates independently about a first horizontal axis parallel to the horizontal axis of the film holder when the film holder rotates about its horizontal axis, and about a second horizontal axis perpendicular to its first axis when the film plane rotates about its vertical axis.

Abstract: A self-clocking three-part encoded data stream is recorded on a magnetic media during a velocity varying period of time. The recording device encodes clock and data pulses. The polarity of the clock and data pulses are requried to be known in order to correctly decode the encoded information. Without this polarity information, the equipment manufacturer will be tightly constrained to maintain the proper coil wiring convention to ensure the correct pulse polarity for the decode process. The Data Alignment scheme provides a reliable method for detecting the encoded data and clock pulse polarity.
