TAPE ADJUSTMENTS

a. Adjusting Azimuth

l Be sure to clean the heads before attempting to make any adjustment. l Be sure both channel’s waveform are the same for the phase matching. l Be sure both channels (1 and 2) are the same level using a dual-channel oscilloscope. l After completion of the adjustment, apply the threadlock (TB-1401B) to the azimuth adjustment screws to fix them securely.

Load an azimuth adjustment test tape (W-f-703 etc., 10
