Abstract
A back-space editing control circuit comprises a sampling signal producing circuit for producing a sampling signal from a control signal reproduced from a magnetic tape in an assembly state and for producing a sampling signal from a capstan motor rotation detection signal in a recording state, a trapezoidal wave signal producing circuit for producing a trapezoidal wave signal from a signal based on a synchronizing signal in the assembly state and for producing a trapezoidal wave signal from the rotation detection signal in the recording state, and a driving and control circuit for sampling the trapezoidal wave signal from the trapezoidal wave signal producing circuit by the sampling signal from the sampling signal producing circuit and for driving and controlling a rotational phase of a capstan motor by use of a sampled signal.
