  • Method of manufacturing the magnetic film having a multiple-axis
    Publication number: 20040115461
    Abstract: The present invention relates to a method of forming the magnetic film having a magnetic easy axis in a pre-formed area. Especially, the present invention related to a method of forming a multiple magnetic easy-axis in a pre-formed magnetic film. It is an object of the present invention to overcome the drawbacks of the conventional magnetic film and to achieve ultrahigh density of the unit recording cell using the magnetic film. It is another object of the present invention to suggest a method of forming a magnetic film and a magnetic film device in which the exchange interaction and the magneto-static interaction between the neighboring areas are eliminated in order to accomplish ultrahigh density for storing data. The present invention presents first, a method of forming a uniaxial magnetic easy axis on the magnetic film. The magnetic moments of the treated recording area having an easy axis are automatically aligned to the axis without an external magnetic field.

  • Magnetic film having a magnetic easy-axis or a multiple easy-axis and a method of manufacturing the magnetic film
    Publication number: 20010031374
    Abstract: The present invention relates to a magnetic film having a magnetic easy axis in a preformed area, and a method of forming the magnetic film Especially, the present invention relates to a method of forming a multiple magnetic easy-axis in a preformed magnetic film and a magnetic film having multiple easy-axis by the same method of forming the multiple easy axis. It is an object of the present invention to overcome the drawbacks of the conventional magnetic film and to achieve ultrahigh density of the unit recording cells using the magnetic film. It is another object of the present invention to suggest a method of forming a magnetic film and a magnetic film device in which the exchange interaction and the magneto-static interaction between the neighboring areas are eliminated in order to accomplish ultrahigh density for storing data, The present invention presents first, a magnetic film (or area) having a magnetic easy axis and a method of forming a magnetic easy axis on the magnetic film.
