摘要：<p>PURPOSE:To obtain the tiled tape guide post constantly maintaining high guiding accuracy without increasing the tension of a magnetic tape by forming a superconductive material at the contact surface of a magnetic recording medium. CONSTITUTION:A magnetic tape 2 is wound at a prescribed angle to a fixed tape guide post 1 formed with the superconductive material. A magnetic flux 3 generated from the magnetic tape 2 does not enter the inside of the fixed tape guiding post 1 formed with the superconductive material due to a Meissner effect, and the magnetic tape 2 and the fixed tape guide post 1 repulse each other. That is, slight clearance exists between the magnetic tape 2 and the fixed tape guide post 1. Thus, sliding frictional force does not work, the increase of the tape tension can be prevented, and the saving of energy consumption for the magnetic recording and reproducing device is realized.</p>
