ABSTRACT:
A disk drive controls the rotational speed of a disk to an appropriate value. A system controller of the drive stores data read from a disk and read-ahead data into buffer memory. A time interval ti at which the buffer memory becomes full is measured, and the time interval ti is compared with a predetermined lower limit value t1and a predetermined upper limit value t2. When a relationship of ti>t2stands, rotational speed is increased. When a relationship of ti<t1stands, control is performed in such a way that the rotational speed is decreased so as to achieve t1≦ti≦t2.
