The wavwforms are those measured with the oscilloscope set as
shown below.
• VOLT/DIV : 50mV
• TIME/DIV : 5ms
• Waveform when tracking gain is lowered.
Fundamental wave appears (large waves).
• Waveform when fundamental wave disappears (no large waves).
• Waveform with no traverse waveform during 100 track jump.
(Brake application is smooth because of adjustment.)
• Waveform with traverse waveform during 100 track jump.
(Brake application is poor because of adjustment.)
