を同時に図ることができる。In FIG. 1, the rotation shaft of the fan 52 is connected to the rotation shaft of a spindle motor 56 mounted on the magnetic disk drive 4 via a gear mechanism (not shown).
Reference numeral 3 denotes a driving unit that rotates the spindle motor 56 according to an external signal. When the drive unit 3 drives the spindle motor to rotate, the rotation shaft of the medium 55 and the rotation shaft of the fan 52 to which the rotation force has been transmitted via the gear mechanism rotate simultaneously. Thus, the medium 55 and the fan 52 of the magnetic disk drive 4 are rotated by one motor. According to this, since only one motor is required, it is possible to simultaneously reduce the size of the housing, reduce the power consumption, reduce the amount of heat generation, and reduce the cost.

的に伝達されないように制御することも可能となる。More specifically, the fan 52 is fixed at a position where it can be seen through a hole formed in the housing 51 so that contact of foreign matter with the fan 52 does not affect the rotation of the medium 55. Are sealed with a net 8 from the outside of the housing 51 with air permeability. Here, the rotation axis of the medium 55 and the rotation axis of the fan 52 may be formed by a single member with a common central axis. In this case, the number of parts can be further reduced, but this can contribute to a reduction in manufacturing costs. On the contrary, the rotating shaft of the medium 55 and the rotating shaft of the cooling fan 52 are provided independently, and the rotating force of the spindle motor 56 is transmitted through a plurality of gears to rotate the rotating shaft of the medium 55 and the rotating shaft of the cooling fan 52. You may make it transmit individually to a shaft. In this case, even when a defect occurs on either the side of the medium 55 or the side of the fan 52, one of the defective portions can be replaced, which is economical. Further, it is possible to control the rotational force of the spindle motor so as not to be selectively transmitted to the rotational axis of the fan or the rotational axis of the medium by operating the gear mechanism by the electromagnetic clutch or the like.

却構造を提供することができる。The present invention is constructed and functions as described above. According to this, the spindle motor is used as the drive source of the fan, so that only one motor is required. It is possible to simultaneously reduce the power, the amount of heat generated, and the cost. According to the second aspect of the present invention, the number of parts can be further reduced by integrally forming the rotation shaft of the medium and the fan.
This can contribute to a reduction in manufacturing costs.
