Definitions

  • the marking device is such that the magnetic regions directly bound one another in the predetermined direction. This does not exclude an arrangement in which the magnetic regions are also spaced from one another in the preferred direction whereby the regions between the magnetic regions can be formed as nonmagnetizeable.
  • FIG. 6 an apparatus for producing a marking device by means of inclined vapor deposition in two deposition directions
  • the magnetic field sensor 31 and the ferromagnetic layer 23 match each other in shape so that the saturation field corresponds to a field stretch in which the characteristic lines of the magnetic field sensor 31 are linear to enable a distinction between saturation of the coding and saturation of the magnetic field sensor.
  • a further possibility is overcoming the saturation problem of several magnetic field sensors, for example, inductive or magneto-resistive magnetic field sensors is for the saturation field to be applied in a direction which does correspond to the sensitive region of the magnetic field sensor.
  • a magnetic field sensor which is suitable for detection of the local magnetization of the layer, for example (a magneto-optical detection device) to exclude influence on the external field on the sensitivity of the magnetic field sensor.
  • the apparatus 71 has three vapor deposition stations 72 , 73 , 74 , whereby the vapor deposition stations 72 , 73 , 74 have support rolls 75 , 76 , 77 associated with them and which, in their lower regions, are flanked by rerouting rollers 78 , 79 or 80 , 81 or 82 , 83 . Above the support rolls 75 , 76 , 77 , respective vapor deposition devices 84 , 85 , 86 are arranged.
  • the carrier foil 89 then travels horizontally to the next rerouting roller 80 and combines their with the second masking foil 95 . Both then travel on the support roll 76 .
  • a second ferromagnetic layer 100 is vapor deposited on the carrier foil 89 with a second direction different from the first.
  • This deposition on the carrier foil 89 is also delimited to the regions of the cutouts 97 .
  • the cutouts 97 are so arranged that they leave on the carrier foil 89 only regions free which are covered in the first coating station by the masking foil 91 there. Because of the different vapor deposition directions of the vapor deposition devices 84 and 85 , regions are produced with different directions of the easy axis of magnetic anistropy.
