1.2.3 Track Jump

The system selects a track jump method according to the target number of tracks to move from the following three schemes:

Interval Jump, Multi Jump, and Traverse Seek.

1. Interval Jump

Detailed seek is possible because this scheme repeatedly performs track jump by 1 track. This scheme is selected when

it is close to the target track or it conducts a seek operation to an adjacent track.

2. Multi Jump

It counts the both edges of a Track Cross Signal TKC and moves by the specified number of track count.

It also drives the CRG motor according to the number of jump.

3. Traverse Seek

By counting the track according to the Track Cross Signal TKC and measuring the time of TKC, it controls the movement

speed and performs the seek operation. At the same time, it minimizes the vibration in the pick-up that will occur during

movement.

Here is the common jump switching setting between DVD and CD.
