ABSTRACT:
A pickup driving system for an optical disk apparatus is disclosed for moving a pickup unit across tracks of a rotating optical disk to read data at a target track position on the optical disk while avoiding drive motor instability, and errors caused by position overruns and underruns. A pulse voltage is superposed on the driving voltage of the drive motor for driving the pickup unit at predetermined intervals (defined by the pulse train) toward the target track position.
