Abstract

Image data is recorded in successive turns on a rotatable record medium driven at substantially constant linear velocity by converting a first of successive image frames of image data to an intraframe code signal, converting the (n-1) next-following frames to (n-1) interframe code signals, and recording the intraframe and (n-1 ) interframe code signals on the record medium. In one embodiment, n is the maximum number of image frames that can be recorded in the innermost turn of the record medium and n is constant for all turns, whereby the same number (n--1 ) of interframe code signals separate successive intraframe code signals from turn to turn. In another embodiment, n is a variable and increases as the radius of the turn in which the code signals are recorded increases, whereby a larger number (n-1) of interframe code signals separate successive intraframe code signals as the turn radius increases. The recorded image data is recovered by reproducing the recorded intraframe and interframe code signals and selectively coupling the reproduced code signals to an intraframe decoder or to an interframe decoder as a function of whether intraframe or interframe code signals are reproduced.
