3.Digital Block
3.1 Description
Digital block is transferred serial data by micom and 8-bit serial data is converted to parallel data by
serial to parallel register. This data is decoded by latch signal. The status output of focus servo,track-
ing servo,and sled servo system,etc is determined by each data. The auto-sequence function process
2~4 micom command by one auto-sequence command.
