PURPOSE:To decrease the influence of demagnetizing fields and to permit high density recording by setting the orienting direction of magnetic particles in the magnetic coating film on a substrate in the direction inclining with respect to the traveling direction. CONSTITUTION:The orienting direction of magnetic particles is set in the direction inclining in the traveling direction (a) with respect to a magnetic head, and recording and reproducing are performed along the direction (a). If the magnetic tape and magnetic particles are oriented in such a way that the orientation direction attains >=theta=10 deg. with respect to the longitudinal direction, the influence of demagnetizing fields is decreased and the reproduced outputs begin to be improved as compared to conventional magnetic tapes oriented to the above- mentioned theta=0 deg.. At theta=60 deg., the magnetic fluxes that the magnetic head can sense decrease and conversely the reproduced outputs are decreased. Therefore, the range of the theta is preferably 10-60 deg., more preferably 15-45 deg., at which the magnetic recording medium deals suffciently with recording at short wavelengths without receiving the influence of demagnetizing fields. |
