Abstract

A reproduced voltage and the surface level difference between magnetic metal layers and substrates were measured directly. During the measurement of the reproduced voltage, the level difference grows depending on the characteristics of the magnetic tape. The spacing loss is proportional to the level difference. The level difference, therefore, is one of the most important causes of the spacing loss. The same results are found in various magnetic tapes. The spacing losses in recording and in reproducing were measured separately and were found to be proportional to the level difference. The spacing loss factor in reproducing is about two times larger than in recording
