Fig. 3-5-(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 ($17) should be sent beforehand because they are
not performed.
1-track jump
When $48 ($49 for REV) is received from the CPU, an FWD (REV) 1-track jump is performed in accordance
with Fig. 3-6. Set blind A and brake B with register 5.
10-track jump
When $4A ($4B for REV) is received from the CPU, an FWD (REV) 10-track jump is performed in
accordance with Fig. 3-7. 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, 5 tracks have been counted through CNIN, and
the brake is applied to the actuator. Then, 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), and the tracking and
sled servos are turned on.
2N-track jump
When $4C ($4D for REV) is received from the CPU, an FWD (REV) 2N-track jump is performed in
accordance with Fig. 3-8. 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, an FWD (REV) N-track move is performed in accordance
with Fig. 3-9. 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.
