ABSTRACT:
A disc apparatus includes a micro-computer. The micro-computer predicts a number of tracks for deceleration from a total number of tracks to be jumped, to thereby calculate a number of tracks for acceleration from the number of tracks for deceleration and the total number of tracks. A thread motor is accelerated until a number of tracks being jumped becomes equal to the number of tracks for acceleration. Thereafter, the thread motor is decelerated to a rotational speed lower than a determined value.
