§4-8. TRK (Tracking) and SLD (Sled) Servo Control
TRK and SLD servo is controlled by the 8-bit command $2X. (See Table 4-3.)
When the upper 4 bits of the serial data are 2 (Hex), TZG is output from the SENS pin.

TRK Servo
The TRK JUMP (track jump) height can be set with 6 bits (D13 to D8) of $36.
In addition, when the TRK servo is on and D17 of $1 is set to 1, the TRK servo filter assumes gain-up status.
The filter also assumes gain-up status when vibration detection is performed with the LOCK signal low and the
anti-shock circuit (described hereafter) enabled.
The gain-up filter used when TRK has assumed gain-up status has two types of structures which can be
selected by setting D16 of $1. (See Table 4-5.)
SLD Servo
The SLD MOV (sled move) output, composed of a basic value from 6 bits (D13 to D8) of $37, is determined by
multiplying this value by 1

magnification set using D17 and D16 when D19 = D18 = 0 is set
with $3. (See Table 4-4.)
SLD MOV must be performed continuously for 50μs or more. In addition, if the LOCK input signal goes low
when the SLD servo is on, the SLD servo turns off.
Note)
When the LOCK signal is low, the TRK servo is set to gain-up status and the SLD servo is turned off by
the default. These operations are disabled by setting D6 (LKSW) of $38 to 1.
