ABSTRACT:
A helical scan type digital recording/reproducing apparatus arranged such that data corresponding to m fields/frames are divisionally recorded in n tracks on a magnetic tape and a slow, still or frame advance reproduction mode is effected in response to an instruction from an external input. The apparatus is equipped with a signal processing circuit coupled to a rotary head for inputting data reproduced from the magnetic tape by the rotary head to store the reproduced data in a memory. In response to the instruction for the slow, still or frame advance reproduction mode, the signal processing circuit outputs a control signal when the data corresponding to one or more frames/fields are stored in the memory. Also included is a servo circuit coupled through a signal line to the signal processing circuit to be responsive to the control signal from the signal processing circuit. The servo circuit controls a capstan motor in accordance with the control signal and the reproduction mode instruction.
