ABSTRACT:
A disk drive device is disclosed including a supporting mechanism for supporting a plurality of magnetic disks, a single motor, and a transmitting mechanism. The supporting mechanism comprises a plurality of bearing mechanisms, each of which rotatably supports each of the magnetic disks, respectively. Each bearing mechanisms is formed as a tube, and a rotatable shaft is connected to each disk and rotatably supported in each tubular bearing mechanism. The rotatable shaft is provided with grooves which generate a pumping effect when a fluid is passed therethrough, whereby the rotatable shaft is supported in the tubular bearing mechanism without friction therebetween. The transmitting mechanism comprises an endless belt for transmitting a rotation of the motor to the supporting mechanism.
