  • Adjustment Of The Magnetic Head Position Track Following On Tapes (AREA)

Abstract

PURPOSE: To obviate the occurrence of stepwise differences between heads at the recording by detecting the recording track of one head at the first of recording and determining the scanning tracks of other head in a VTR of helical scan type.
CONSTITUTION: Video signal Sy is made to FM signal SF which is then supplied to the recording side contacts R of recording-reproducing changeover switches 21A, 21B. At the recording, the recording track of one head 22A is detected in the initial stage of recording, thereby the scanning truck of the other head 22B is determined. Because of this, the head 22B roughly follows the track having been recorded with the head 22A in the previous field and scanning is performed under application of vibrations. At the time when the head 22B ends scanning of 1 field, the center of the scanning track of the head 22B and the center of the track recorded with the head 22A align. Thereby, the track pitch at the recording is accurately determined and good recording accomplished even in such a case when a stepwise difference occurs between the heads owing to the residual distortion, etc. at the reproducing.
