Abstract
An average write speed M is calculated by averaging write speeds for blocks of a tentative block size La, and write speed variation σ of the blocks with respect to the average write speed M is calculated (Step S). A maximum speed Vmax is calculated by accelerating and then decelerating (or decelerating and then accelerating) a stage when moving the stage by the width of one of the blocks of the tentative block size La (Step S). When the relationship 'Vmax−M≧σ' does not hold, the tentative block size La is increased (Step S). When the relationship 'Vmax−M≧σ' holds, the tentative block size La is set as an optimal block size Lb (Step S).
