Dynamic Deflection of Magnetic Tape Due to Rotating Head Scanning

概要

論文の詳細を見る
Steady state deflection of cylindrical magnetic tape due to rotating head scanning is theoretically and experimentally investigated. The deflection is analyzed taking bending stress, tension, inertia and damping into consideration. The analysis shows that wavy deflection is caused both before and behind the head under some scanning conditions. The critical conditions and the effect of the scanning conditions on the wavelength and damping ratio are closely analyzed. An experiment is made on a transverse recording device and the results are compared with the theoretical results. As a consequense, in the wave length, the experimental results agree with the theoretical ones, where the damping force is calculated from the squeeze effect of an air film between the tape and the head rotor.
