  • Abstract
    In this paper the mechanism of CrO2video tape headwear is described. In tapes which contain only CrO2, headwear increases with increasing hardness of the coating. Hardness is characterized by the Young´s modulus. By employing the soft ZnO pigment in magnetic CrO2tapes, it is possible to regulate headwear (H.W.) in the desired range of 0.5<H.W.<1 μm per 100 hrs. playing time in VHS recorders. This means that the use of CrO2/ZnO results in the unique situation of low headwear, no rubbing noise and no head clogging problems.
