Active = " H "
Non-active = "L"
1) In test mode:
Timer Clock Adj [transmit mode] : H --> L
O
Timer Clock Adj [receive mode] : L --> H
2) Other than test mode : always L
Common Output = For DVD, Output = High
O
Common Output = For VCR, Output = Low
As for DVD/VTR during P.Off, Output = Low
Video Head Switch Signal
( During L'/R = "H", during R'/L = "L" )
Cylinder FG= 1 or 4, Ref time taken as Input time until PGMM time.
Timing calculation is performed based on the following.
O
