(2) The TJ Command
When the track jump command is input to the servo command an acceleration pulse is generated (period a), following
which a deceleration pulse is generated (period b), after which the specific jump is completed after the brake period
(period c) elapses. In this break period the beam slip direction is detected through the TES and HFL inputs, and the
segment of the TES signal that propagates the internal slip is cut by TOFF. Moreover, by increasing the servo gain
using TGL, it is possible to lock onto the track that is the jump destination. In the JP pulse interval TOFF output
mode, TOFF is high during the interval when the JP pulse is generated.
* The TOFF pin is only low when the CLV mode is active when related to the disk control mode, and this terminal is
high during start, stop, and break control. Moreover, the TOFF pin can be turned on and off independently using
commands. However, the disk motor control is only enabled when the CLV mode is active.
