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

Abstract

PURPOSE:To make a head locus at the time of recording coincide with a head locus at the time of reproducing and to stabilize a tracking at the time of reproducing by voltage-driving a driving part at the period related to the rotation period of a rotary drum and in the vicinity of a mechanical resonance frequency. CONSTITUTION:At a driving part 4a of a rotary drum control device, a head 5 is arranged which is cooperated with a coil arranged in a magnetic circuit and can be displaced in the shaft direction of a magnetic tape 13, and to the driving part 4a, the current is supplied from a contact 14. An electrode 15 is brought into contact with the contact 14 simultaneously a coil is connected. The head 5 is electrically connected to an upper transformer 7 and a lower transformer 8 is magnetically coupled and faced to the transformer 7. Transformers 7 and 8 and the driving part 4a are housed and arranged in an upper drum 3. The driving part 4a of the control device is voltage-driven at the period related to the rotation period of the rotary drum and at least in the vicinity of the mechanical resonance frequency, and the head locus at the time of recording is made coincident with the head locus at the time of reproducing.
