Abstract
A head arrangement and head offset are set so that the track pattern continuously recorded on a continuously running tape will be ordered in the sequence of recording when taken along the time dimension. In intermittent-feed still-speed recording, recording information is divided for recording, and the magnetic tape is fed momentarily by a distance equal to the tape amount recorded. In a helical scan magnetic recording and reproducing apparatus, intermittent still-speed recording is performed at prescribed intervals of time, and playback is performed with conditions that satisfy .vertline.v.vertline..ltoreq.r/N (N: positive integer, v: real number, r: positive real number) when the magnetic tape is played back at a speed v times as fast as normal playback speed and the rotary drum is rotated for playback at a speed r times as fast as recording speed. A digital playback head and an analog playback head are mounted on the same rotary drum, and the playback mode is automatically switched to play back a tape on which both analog and digital signals are recorded.
