Non-contact tape tension measurement and correlation of lateral tape motion and tape tension transients
نویسندگان
چکیده
Non-contact tension measurement of magnetic tape is performed. Light from a focussed light source is directed at a tape surface and the light reflected from the tape is captured by a photo cell. As the tape tension varies, the divergence of the reflected light bundle changes, i.e., the amount of light seen by the photo cell is a measure for the tension in the tape. Using this noncontact tension measurement approach and a high frequency lateral tape motion sensor, we have investigated the correlation between high frequency tension changes and high frequency lateral tape motion. Strong correlation is observed between the absolute values of tension and lateral tape motion.

Correlation of Lateral Tape Motion and Tape Tension Transients
Introduction High frequency lateral tape motion (LTM) is a problem in tape technology that limits track density in a tape drive. To reduce high frequency LTM, it is important to identify all sources of lateral tape motion. The most important sources of high frequency LTM are edge contact between tape and tape drive components, non-repeatable roller axial run-out, air induced flutter and tape te...

The sources of lateral tape motion in a tape drive are reviewed. Currently used measurement methods and models for lateral tape motion are analyzed and compared. The effect of roller run-out, tape edge contact, and tape tension transients on lateral tape motion is discussed. A dual stage actuator tape head is investigated to improve track-following capability and increase the track density on a...
متن کاملAttenuation of lateral tape motion due to frictional interaction with a cylindrical guide
Lateral tape motion (LTM) is a function of tape path and tape properties, design parameters such as speed, tension, and friction between tape and tape path components. This investigation deals with the LTM of a tape moving over the surface of a cylindrical guide. Starting from the equation of motion for a moving tape on a cylindrical guide surface, the effects of friction, tape properties and d...

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...
