Title: Disk-type storage medium driving apparatus and disk-type storage medium rotation speed control method

Abstract: A rotation speed of a disk-type storage medium is suitably controlled in order to save power and to reduce noise in a disk-type storage medium driving apparatus provided with one or more communication interfaces. A disk-type storage medium driving apparatus that can switch rotation speed of a disk-type storage medium, to drive the disk-type storage medium, includes one or more communication interface units, which perform data transfer to and from peripheral devices; and a control unit that judges necessity of switching a rotation speed of the disk-type storage medium when there occurs a data transfer request through one of the communication interface units.
