In the magnetic recording/reproducing apparatus configured to run the tape and record the information signal again from a third timing position immediately before the first timing position that is the end of the signal recording portion of the tape, a first reference signal generating means for generating a first reference signal for capstan rotation control during a period from the second timing position to the third timing position; a second reference signal generating means for generating a second reference signal for capstan rotation control in a period after the third timing position, and a period from the second timing position to the third timing position. A splicing device for a magnetic recording and reproducing device, characterized in that the pulse synchronized with the capstan rotation detection signal is configured to match the phase of the second reference signal.
