Abstract

To enable higher recording density and data access accuracy, controlling lateral tape motion within high precision specifications through calibrated tape tension control is one of many key focuses for extra high density magnetic tape drives. This paper presents a novel rotary actuation mechatronic system which regulates travelling tape tension in a modern tape drive by dynamically alternating its tape path through closed-loop controls. Effectiveness of the system was demonstrated through calibrated laboratory parametric studies from which variation of travelling tape tension was found to be significantly reduced. The work described herein suggests engineering feasibility of using flangeless guiders in modern advanced tape drives as well as tape tension control without regulating tape drive’s driving motors.
