Abstract
A data recording/reproducing method for a so-called near video-on-demand for time-differentially distributing motion picture films or the like. When recording continuous data of, for example, a cinema program, the data is split into, for example, 12 channels CHA to CHL. The channel data is further split into 2400 portions, while the data of the 2400 portions associated with the respective channels are re-arrayed to form blocks BL.sub.0 to BL.sub.2399 for each channel. The block data is recorded on a recording medium so that the blocks will be arrayed in the sequence of blocks BL.sub.0, BL.sub.2339, BL.sub.1, BL.sub.2338, . . . BL.sub.1200. For data readout from the recording medium, every second blocks are read out, beginning from the block BL.sub.0. After reproducing the block BL.sub.1119, every second blocks are read out in the reverse direction beginning from the block BL.sub.1000 for data reproduction.
