The Influence of Operating and Design Parameters on the Magnetic Tape/guide Friction Coefficient
نویسندگان
چکیده
The friction coefficient between a guide and a tape sample is determined experimentally as a function of nominal tension, speed and guide radius. A comparative study between metal particulate and metal evaporated tape is performed. The tape/guide contact pressure correlated to the experimental results. Tape temperature measurements are compared with the experimentally obtained friction coefficients. Introduction The classical belt/pulley equation relates the “tight-side” tension 1 T (upstream of pulley) to the “slack-side” tension 2 T (downstream of pulley) as an exponential function of the product of the friction coefficient μ and the belt/pulley contact angleθ .

Reducing the Magnetic Tape/guide Friction Coefficient by Laser Surface Texturing: Experimental Analysis
The friction coefficient is an important parameter in designing magnetic tape transports. We have introduced laser surface texturing to reduce the friction coefficient between guides and magnetic tape. The surface features enhance the formation of an air bearing and hence, reduce the friction coefficient. INTRODUCTION Lateral tape motion (LTM) is defined as the time-dependent motion of the tape...
