During this adjustment, the oscilloscope changes in units of about 2%. Adjust so that the waveform comes nearest to
the specified value. (MO groove read power traverse adjustment)
Notes:
1. Data is erased during MO write when a recorded disc is used for this adjustment
2. If the traverse waveform is difficult to be monitored, connect an oscilloscope as shown in the figure below.
