AMPLITUDE DISTORTION
The non-linear relationship between the magnetism residing on the tape and the magnetic field inducing it, will cause considerable amplitude distortion in the recording.
The curve OB3B5 in Fig. 11.4 shows a typical relationship between the magnetisation produced in a magnetic material and the increasing magnetic field produced in it. A field strength of H2 units, for example, would produce a degree of magnetisation corresponding to the point B2, provided the material was unmagnetised initially, and also provided the field strength was not, at any time during its general increase from zero to H2, caused to diminish. The levels of magnetisation corresponding to Bl, B2, etc. are those obtaining when the field strengths are actually ...
