- Adjustment Of The Magnetic Head Position Track Following On Tapes (AREA)
Abstract
PURPOSE: To make high-precision tracking possible by recording two kinds of control signals, bearing a fixed relation, on both sides of a track when information is recorded and then by controlling an information head position by using the above- mentioned signals in reproduction.
CONSTITUTION: In addition to video head 30, magnetic head part 6 is provided with tracking heads 31 and 32 which record tracking control signals. As a result, two kinds of control signals differing in frequency while their frequencies are continuous to each other and bearing the reverse relation between tracks are recorded on both sides of respective tracks T1, T2... in video recording. When f1 and f2 are recorded on the upper side and lower side of the 1st track T1 in the figure, recording on the 2nd track T2 is carried out reversely. For the purpose, position control over head part 6 is exercised by a fixed circuit reproducing evenly signals f1 and f2 by head 30 in reproduction, so that accurate tracking will come into effect.
