Abstract
In an optical disk storage, the seek of an optical head is controlled so that the number of seek times cannot exceed a threshold number of times in a predetermined period or an accumulated seek period cannot exceed a threshold period in a predetermined period. Therefore, a wasteful power consumption and a rise in the internal temperature associated with the seek activity can be effectively prevented.
