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

Abstract

PURPOSE:To suppress the level of a reproducing signal from being lowered in spite of the change of tape feed speed, by displacing plural heads in the width direction of a tape, respectively, in the case of performing reproduction at different speed. CONSTITUTION:Plural driving parts 4a and 4b consisting of a coil and heads 5a and 5b displaceable in the width direction of the tape 13 cooperating with the coil, an upper transformer 7 to which each of the head 5a and 5b is connected electrically, respectively, and a lower transformer 8 confronted with the upper transformer and coupled magnetically are housed and arranged in a rotary drum 2. And a device is constituted so that a control current can be supplied to each of the driving parts 4a and 4b, respectively, via a resistor, a contact 14, and an electrode 15 inserted respectively to each of the control sides of the plural driving parts 4a and 4b, and also, it is constituted so that the non-control sides of the plural driving parts 4a and 4b can be used commonly in a movable part and are connected to reference potential via a pair of electrode and contact. In such a way, it is possible to displace the heads 5a and 5b mechanically in the width direction of the tape via a magnetic reaction by cooperating with the coil, and to conform a head locus with a recording locus at the time of the reproduction with in each of the heads 5a and 5b.
