HIGH-DENSITY MAGNETIC RECORDING PROPERTIES OF EVAPORATED Co-Ni-O THIN FILM

抄録

  The Co-Ni-O thin film formed by the CVI process has a columnar structure that slants diagonally in relation to the substrate. It is known that, for the reasons described above, the film has no easy-to-magnetize direction within the plane and that there is a directionality in output reproduction. [1], [2] The orientation of the easy-to-magnetize direction of Co-Ni-O thin film has been analyzed.
 
  The head has also been studied with the objective of fully exploiting the potential capability of the recording medium. In addition, a method for reducing magnetic noise, a problem involving the recording medium itself, has been discussed.
