Fig. 4-3-(b). Auto Focus Timing Chart
(b) Track Jump
1, 10, and 2N-track jumps are performed respectively. Always use this when focus, tracking, and the sled
servo are on. Note that tracking gain-up and braking-on should be sent beforehand because they are not
performed.
1-track jump
When $48 ($49 for REV) is received from the CPU, a FWD (REV) 1-track jump is performed in accordance
with Fig. 4-4. Set blind A and brake B with register 5.
10-track jump
When $4A ($4B for REV) is received from the CPU, a FWD (REV) 10-track jump is performed in accordance
with Fig. 4-5. The principal difference between the 10-track jump and the 1-track jump is whether to kick the
sled or not. In addition, after kicking the actuator, when 5 tracks have been counted through CNIN, the brake
is applied to the actuator. Then, when the actuator speed is found to have slowed up enough (determined by
the CNIN cycle becoming longer than the overflow C set in register 5), the tracking and sled servos are
turned on.
2N-track jump
When $4C ($4D for REV) is received from the CPU, a FWD (REV) 2N-track jump is performed in accordance
with Fig. 4-6. The track jump count “N” is set in register 7. Although N can be set to 2
16
tracks, note that the
setting is actually limited by the actuator. CNIN is used for counting the number of jumps.
Although the 2N track jump basically follows the same sequence as the 10-track jump, the one difference is
that after the tracking servo is turned on, the sled continues to move only for “D”, set in register 6.
N-track move
When $4E ($4F for REV) is received from the CPU, a FWD (REV) N-track move is performed in accordance
with Fig. 4-7. N can be set to a maximum of 2
16
tracks. CNIN is used for counting the number of jumps. This
N-track move uses a method in which only the sled is moved, and is suited for moves over thousands of
tracks.
