In a helical-scan recording system, multi-channel data transfer requires many heads aligned precisely in a scanner. A single-tip multi-head greatly facilitates this alignment. The new multi-head, combined with an ETF (Embedded Thin Film) head reported previously, has much smaller magnetic cores than a conventional multi-head. This minimizes the crosstalk that is an inherent problem in the multi-head. Head-tape contact for gapto-gap distance up to 900 km has successfully achieved by adjusting the tip-radius and head protrusion.

In this study, air pressures distribution around the rotating drum was measured using minute differential pressure meters that are composed of semiconductor pressure sensor and extended flexible probes. Computational simulation of the pressure and vortex inside and outside of the rotating drum was evaluated also, taking into account the effects of inner head mounting bases, holes and head mounting windows.

“…The floating and the contact phenomena between the tape and the head or the drum can be treated as an airbearing problem coupled with a problem of the thin shell equation in FEM. Air ftlm was treated by the modified Reynolds equation with slip flow and the averaged fluid thic1rness [2,3,4].…”

In a helical scan VI'R system, the defonnation of the magnetic tape due to the magnetic head protrusion affects the recording characteristics. The reproduced waveform envelope changes delicately because of the changes of head-to-tape contact condition from the inlet through the outlet of the helical rotating drum. We proposed a new analysis technique of the head-to-tape contact and the reproduction envelope by the structure/fluid coupled analysis considering the elasto-hydrodynamic lubrication. We have made the computational simulation of reproduced envelope deterioration by the Finite Element Method. The difference between the upper drum rotating mechanism and the middle drum rotating mechanism are discussed
