Record disc addressing apparatus |
摘要 |
A record disc reproducing apparatus determines the magnitude and polarity of the difference between a preselected data address and a current data address and moves a pickup assembly in a direction to reduce that difference until it drops below a prescribed address tolerance. The amount of movement can either be a given distance or some fraction either of the difference between the current and prescribed data addresses, or of the breadth of a program portion.
