Description of Functions
Pre-amplifier
This is a low noise amplifier for amplifying the signals from the heads with an emitter follower output.
The RDX and RDY are the outputs of the differential amplifier whose polarity between the RDX and X side of
the head input is same.
Mode control
The mode are set as shown Table 1 by CE and XCE.
