1. Move the head until it arrives at TRK 01. (Do not move
the head passing TRK 01. If the head arrives at TRK 00,
through the Cat's eye pattern signal is to be rechecked
and then the head is to be set on the TRK 01.)
The output signal level of CN I 07-5 is 3 V or more.
2. Move the head until it arrives at TRK 00.
The output signal level of CNI07-5 is 0.7 V or less.
1. The DSKCHG indicator lights.
1. When the WRITE switch is pressed and "2F", "IF", or

2. Set the SIDE SELECT switch to side 1, and "2F",
"IF", or "WCP (M/W)" are written, the corresponding
