skip pulse s 13 from the track skip detector 13 note that the rotary head a indicates the rotary heads a 1 and a 2 and similarly the rotary head b indicates the rotary heads b 1 and b 2 further the rotary head 1 indicates the rotary heads a 1 and b 1 and the rotary head 2 indicates the rotary heads a 2 and b 2 the fm demodulator 14 demodulates the audio signal selected at the head switch 12 and inputs the same to the waveform connector 15 the waveform connector 15 smoothly connects the signal fm demodulated at the fm demodulator 14 while maintaining the continuity and outputs the same as the repaired audio signal to deal with the anomalous state such as the discontinuity of the signal or skip or noise from the timing based on the track skip pulse s 13 detected at the track skip detector 13 details of the high speed reproduction operation of the hi fi video apparatus 1 will be explained next fig3 is a view of the track structure of the tape recording surface of the magnetic tape 18 of a hi fi video apparatus fig4 is a view of the trace of the head at the time of high speed reproduction of the video hi fi audio track of the magnetic tape 18 illustrated in fig3 fig5 is a view of the track structure of the magnetic tape 18 and the head trace at the time of high speed reproduction symbols r 1 to r 7 shown in fig5 are track numbers attached for convenience for the explanation of the present embodiment while symbols q 1 to q 7 are scanning numbers attached for convenience for the explanation of the present embodiment the track skip detector detects the.
