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

Abstract

PURPOSE: To avert squeaking of tape with a simple constitution by vibrating part of the magnetic tape of the portion being put along a stationary drum with a vibrating means.
CONSTITUTION: A window hole or a recess 6 is provided in part of a stationary durm 1b and a vibrating means 5 is contained therein. This enables the tape 4 being put along the lower drum 1b to be tapped from its inner side and to be thereby vibrated. E.g., a bimorph piezoelectric element 5 may be used for the vibrating means 5. The position of θ = 45° where the contact pressure becomes maximum is good as the mounting position of the vibrating means 5 to the drum 1b, in the case of the system in which the tape 4 is put along the drum 1 over a range of nearly 180° with respect thereto. With such constitution, vibrating the vibrating means 5 reduces the tension at the outlet of the tape 4 from the drum 1. Hence, squeaking may be averted with the simple constitution.
