Abstract
A method and apparatus for recording control pulses on a control track are provided. The control pulses correspond to a number M (where M is an integer equal to or larger than four) of azimuthal tracks on the tape on which the number M of segmented data, obtained by dividing image data corresponding to one frame into the number M of segments, are recorded. One period of the control pulses corresponds to a number N (where N is a divisor of M) of azimuthal tracks, and a duty ratio pattern of the control pulses in a number L (L=M/N) of successive periods corresponding to one frame is different in each of a number K (where K is an integer equal to or larger than two) of successive frames.
