イレ，−ズヘッド。FIG. 1 is a signal waveform diagram showing the playback output when erasing is performed using an embodiment of the flying erase head of the present invention, and FIG.
The figure is a schematic diagram to explain the necessity of the flying erase head, Figure 3 is a perspective view showing the arrangement positions of the flying erase head and the recording head, and Figure 4 is the connection between the coil of the flying erase head and the coil of the recording head. A connection diagram showing the relationship, Figure 5A is a signal waveform diagram showing the playback output when erasing is performed using a conventional flying erase head, and Figure 5B is a signal waveform diagram showing the playback output when erasing is performed using only a full erase head. The signal waveform diagram showing the output, Figures 6 and 7 are graphs showing changes in reproduction output using the recording current frequency and erasing current as parameters, and the eighth factor is a graph showing the relationship between erasing current and erasing rate. Figure 9 is a schematic diagram to explain the coordinate system for specifying the magnetic field of the head, Figure 10 is a graph showing the relationship between the depth of the tape and the magnetic field of the head, and Figure 11 is a diagram showing the relationship between the depth of the tape and the magnetic field of the head, and Figure 11 shows the relationship between the depth of the tape and the magnetic field of the head. It is a schematic diagram used to explain the principle of occurrence. 3.3A, 3B... Recording head, 4... Flying erase head.
