ABSTRACT:
In a flexible disk drive having a main frame in which a flexible disk is inserted and a direct-drive motor having a stator disposed on a main surface of the main frame and a rotor including a permanent magnet, a gap between the main surface of the main frame and the permanent magnet is set at a distance so that the rotor does not fall due to gravity by attracting the rotor to the main frame by the magnetic attractive force of the permanent magnet even if the rotor is turned upside down to the stator.
