ABSTRACT:
A data recording and reproducing apparatus of a helical scanning system includes a unit for recording and reproducing an information signal in an oblique information track on a magnetic tape by a rotary magnetic head and a unit for recording and reproducing a control signal on the magnetic tape in a longitudinal direction thereof. Further, the data recording and reproducing apparatus includes a memory unit for storing a difference (X-value error information) between a predetermined X value and a distance (X value) between a record starting position of the information track and a recorded position of the control signal, a unit for recording X-value error information on the magnetic tape individually each time information is recorded, a unit for reproducing X-value error information on the magnetic tape, and a unit for shifting a reproduced phase of the control signal in accordance with the X-value error information.
