ABSTRACT:
Provided is a drive signal generating apparatus including: an arithmetic section that calculates an approximate expression to approximate variations of multiple detected values each representing one of a position of an optical pickup section and an amount of positional deviation of the optical pickup section with respect to a current target position, the position of the optical pickup section being sequentially detected when the optical pickup section moves stepwise toward multiple target positions set in advance on a drawing surface of a drawing target; and a drive signal generation section that generates a second drive signal synchronized with a first drive signal for causing the optical pickup section to move stepwise, the second drive signal having a signal value corresponding to an approximate value calculated by substituting a value associated with each of the multiple target positions into the approximate expression so as to move an optical component provided in the optical pickup section.
