Abstract

PURPOSE: To prevent the thermal-off track phenomenon caused by temperature rise, by installing a fan dissipating the heat at the end of the spindle of a disc and providing an external cover having a heat dissipation fin.
CONSTITUTION: The magnetic disc 1 is borne to be turned with the spindle 2. Air is circulated to the spindle ends 2', 2" extended outside the upper and lower covers 3, 4 of the disc 1, and heat dissipation fans 7, 7' having heat dissipation effect are installed, and external covers 9, 9' providing a number of heat dissipation fins 8 radially at the outside of the upper and lower covers 3, 4, are fitted. The heat dissipation fans 7, 7' are turned with the rotation of the spindle 2 fitting the magnetic disc 1, external air is suctioned from the arrow 10, the heat of the heat dissipation fin 8 is dissipated externally to cool the upper and lower covers 3 and 4. With the constitution like this, the heat produced in the disc chamber is efficiently discharged, and the thermal-off track phenomenon due to the temperature rise is avoided.
