The state of recorded magnetization and reproduced wave form of a metal evaporated tape with high anisotropy were investigated for the case in which the magnetic field direction of the recording head tilted from the normal plane which contained the easy axis of the tape. When the direction of recorded track tilts from the normal plane which contains the easy axis, magnetic charges appear at the track edge because the magnetization has a strong tendency to turn to the easy axis direction. These magnetic charges affect the reproduced waveform; the difference was observed between the reproduced waveforms from both track edges.
