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

Abstract

PURPOSE: To readily adjust the azimuthes of recording heads by connecting a voltage divider and a timing puise generator respectively to the two input terminals of plural comparators and changing the voltages being applied to the voltage divider.
CONSTITUTION: A trigger pulse generating circuit is provided with comparators 6-1 to 6-9. The lead-out points of the voltage divider 7 are connected to the first input terminals of the respective comparators and a timing pulse souce of inclining rise to the second inpput terminals respectively. If the voltages to be applied to the first input terminals of the comparators are let to be E1, E2...E9 respectively, a trigger pulse 1 is formed when the timing pulses reach E1 and a trigger pulse 2 is formed when they reach E2, thus the trigger pulses are formed with a delay of each specified time. since it is necessary to change the delays among the trigger pulses 1, 2,...9 depending upon the angles of inclination of the arraying of recording heads 2-1 to 2-9, only required is to change the voltages +E, -E to be applied to the voltage divider 7. Thereby, the azimuthes of the recording heads may be readily adjusted.
