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

Abstract

PURPOSE:To easily perform the detection of a reference track, by loading a first servo head and a second servo head at an inner peripheral side inner than the first servo head by an interval equivalent to one track pitch confronting with a servo plane. CONSTITUTION:A servo disk is rotated in a rotating device, and the first servo head 30 is confronted with the servo plane of the servo disk, and the second servo head 31 is loaded at a position moved by the interval equivalent to one track pitch to the inner peripheral side inner than the first servo head 30 confronting with the servo plane similarly as the first servo head 30. And when the first servo head 30 advances to an outer guard band 2, a reference track signal is detected by a reference track detecting means, and the second servo head 31 is positioned at the reference track. In such a way, it is possible to shorten a time from the detection of the reference track to the positioning of the servo head.
