Abstract
An information signal recording medium has a spiral track on which an information signal is recorded. The information signal includes picture element data which correspond to one field, and is time-sequentially recorded on the spiral track in terms of the picture element data which correspond to one field. The picture element data which correspond to one field are made up of a plurality of picture element data of a first field and a plurality of picture element data of a second field, among picture element data which are obtained by subjecting an analog video signal to a digital pulse modulation, where the analog video signal corresponds to one frame made up of the first and second fields. A reproducing apparatus is designed to reproduce the second field in a sequence different from a sequence with which the recorded picture element data are reproduced from the information recording medium in the first field.
