Abstract

PURPOSE: To obtain the test tape which can perform the tracking adjustment simply with high accuracy, by respectively recording the single frequency signal of two kinds of difference on the adjacent video tracks and recording the control signal so that the video head can trace the intermediate part of the adjacent tracks.
CONSTITUTION: On the video tracks, the single frequency signal F1 in frequency f1 and the single frequency signal F2 in frequency signal f2 are alternately recorded and on the control track, the control signal C shifted by 1/2 vertical synchronizing period from the timing of signal recording is recorded. The signal C reproduced at the control head 9 of the test tape 1 drives the rotating cylinder mechanism 14 via the amplifier 9 and the servo circuit 16. The video heads 10a, 10b perform trace over two video tracks and display the level differences to the pitch width via the transformers 19a, 19b, amplifiers 20a, 20b, BPF24a, 24b and comparator 26. Accordingly, the amount of shift of the tape running location can accurately be grasped.
