摘要： 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.

摘要： A rotary recording medium has information signals recorded on a spiral or concentric tracks formed thereon as variations in geometrical configuration. The tracks comprise a mixture of digital recorded tracks which are recorded with a first modulated signal and analog recorded tracks which are recorded with a second modulated signal. The first modulated signal is a digital signal which has been time-sequentially multiplexed in terms of blocks at a transmission frequency of 44.1 kHz or a frequency extremely close to 44.1 kHz and has then been subjected to a modulation, where each of the blocks are constituted by a synchronizing signal, error correcting codes, and an error detecting code, which are added to a plurality of channels of digital data which are digitally modulated information signals. The second modulated signal is an analog modulated analog information signal at least including a composite video signal. A number of blocks recorded in one track turn of the digital recorded tracks is approximately equal to a product of the transmission frequency and a duration of one revolution of the rotary recording medium.
