Tracking brake
The chart shows the relationships between the TES, HFL, and TOFF signals during the track jump C period. The TOFF
signal is extracted from the HFL signal by TES signal edges. When the HFL signal is high, the pickup is over the
mirror surface, and when low, the pickup is over data bits. Thus braking is applied based on the TOFF signal being
high when the pickup is moving from a mirror region to a data region and being low when the pickup is moving from a
data region to a mirror region.
JP three-value output
The JP three value output command allows the track jump operation to be controlled from a single pin. However, the
kick gain is 6 dB lower when this pin is used, so applications must increase the gain in the servo system.

Track check mode
The LC78625E will count the specified number of tracks when the microprocessor sends an arbitrary binary value in
the range 8 to 254 after issuing either a track check in or a track check out command.
