Filed: 1989-10-27
Abstract: PURPOSE:To easily reduce the influence of a leaked magnetic field by adjusting a winding ratio between the two kinds of coils for which the direction of the generated magnetic field is mutually inverted. CONSTITUTION:The two kinds of cores 12 are provided so that the direction of the generated magnetic field can be mutually inverted, and the size of the magnetic field generated by the coil, which generates the magnetic field in a direction reverse to the direction of the leaked magnetic field, on a recording medium 2 is made larger than the size of the magnetic field generated by the coil, which generates the magnetic field in the same direction as that of the leaked magnetic field, on the recording medium 2. Further, the winding ratio between the two kinds of the coils is set so that the magnetic field to be generated by each coil can obtain a size to be recorded and reproduced as the result of superimposing the magnetic field with the leaked magnetic field. Thus, since difference between the sizes of the magnetic fields in the both directions on the recording medium is decreased and the magnetic fields in the respective directions obtain the sizes to be recorded and reproduced, the influence of the leaked magnetic field is reduced with simple configuration and recording and reproducing can be executed without fail. Then, the influence of the leaked magnetic field can be easily reduced.
