Abstract
A magnetic recording and reproducing device comprises a rotary head incorporating plural heads having different azimuths and recording and reproducing an input signal by tracing a magnetic tape and a tape feeding drive device for feeding the magnetic tape. The tape feeding drive device feeds the magnetic tape during multiple speed reproduction with a tape feeding speed of about (N+1/2) times (where N is an integer) as high as a tape feeding speed during a normal speed reproduction. Positional relation of head trace to the track thereby is shifted by 1/2 track in each trace with a result that a section in which information such as sub-code can be read and a section in which it cannot be read are dispersed on time axis. This enables the information to be obtained substantially in real time.
