In fabricating Co-Cr films with a continuous vacuum deposition system, incident angle of vapor beam onto substrates affects magnetic properties and recording characteristics of the films. The Co-Cr films deposited with incident angle from 55° to 20° and from 70° to 20° are anisotropic and the films deposited with incident angle from 20° to −20° are isotropic in the film plane. Azimuth angle dependence of reproduced output in these films fairly coincides with angular dependence of Mr, in the film plane. Isolated waveform of the films deposited with incident angle from 55° to 20° has MMF dependence in normal head scanning direction, while in the films deposited with incident angle from 70° to 20° it is independent of MMF either in normal or reverse head scanning direction.
