METHOD FOR CHECKING POSITION OF AUDIO-SIGNAL PLAYBACK MAGNETIC HEAD IN VIDEORECORDER Russian patent published in 1994 - IPC

Abstract RU 2018182 C1

FIELD: magnetic recording. SUBSTANCE: method involves high-frequency signal recording on first track, continuous low-frequency signal recording on second track, and magnetic head position in respect to desired track is determined by upper record edge on second track during absence of signal on first track; inclination angle of magnetic head clearance is determined by change in amplitude of high-frequency signal. EFFECT: facilitated procedure. 5 dwg
