Abstract
Any slight deviation of the VTR head on the track becomes a serious problem when narrower tracks are used to improve the surface and volume recording densities of VTR tape. Therefore it is indispensable to improve the linearity of recording tracks and the precision of playback tracking. In this study, a pilot signal is recorded on the tape at the initial recording time for use as a reference to find the scanning position of the head, and the positions of the recording/playback heads with actuators are controlled so as to align the head scanning trace with the standerized track pattern.
