Abstract

PURPOSE: To reject the variation of carrying amount due to slip caused at the rising of carrying, by recording CTL pulse at the specified position during tape carrying and correcting the detection of rotary angle with this pulse.
CONSTITUTION: In taking the rotary angle of the motor 36 required for one tape carrying as 480 pulses for example, in the memory circuit 69, the latch circuits 53, 58, 66 store data 240, 360, -60 respectively and the counter 62 stores data -120. Accordingly, the motor 36 stops at the position corresponding to 120 pulses from the recording position of CTL pulse and to 480 pulses from the start of tape carrying. Further, since CTL pulse is recorded on tape, even if the amount of slip between the capstan and the tape is changed at recording and reproduction, the error can be corrected at the CTL pulse. Especially, the variation in carrying amount which often produced at the rising of carrying, can remarkably be reduced.
