Figure 1 is an overall plan view, and Figure 2 is a FIG. 3 is an enlarged plan view of the main part, and FIG. 4 is a graph showing the error rate of the reproduced signal when an audio signal is reproduced using a magnetic tape on which the recording pattern shown in FIG. 1 is recorded. 6 to 6 show a first embodiment in which the magnetic recording and reproducing apparatus of the present invention is applied to a VTR, FIG. 4 is a perspective view showing an outline of the tape running mechanism, and FIG. 5 shows a rotating head, a fixed head, and each of them. A diagram conceptually showing the relationship between the magnetic signal recorded on the magnetic tape by the head and the recording pattern. FIG. 6 is a diagram showing the relationship between the magnetic signal recorded on the magnetic tape by the head and the recording pattern. FIG. 7 is a graph showing the error rate of the reproduced signal, and is a diagram conceptually showing the directions of the head gaps of the rotary head and the fixed head in the second embodiment of the magnetic recording/reproducing apparatus of the present invention.

Claims

[Scope of utility model registration request]

A method in which the audio signal is PCM-modulated and recorded on an extension of the video track in an area near one edge of the magnetic tape using two rotary heads, and a fixed head is used to record the audio signal on a track specific to the audio signal at one edge of the magnetic tape. In a magnetic recording and reproducing apparatus that can selectively adopt a method in which: A magnetic recording/reproducing device characterized by:
