A magnetic disc mounting device for use in a magnetic recording/reproducing apparatus in which a center core provided in the central portion of rotation of a magnetic disc is engaged with a rotary drive shaft provided on a main body of the magnetic recording/reproducing appatatus, the magnetic disc is rotated and a magnetic head is moved in the radial direction of the magnetic disc to thereby perform a magnetic recording or reproducing operation. A center core receive member capable of attracting the center core and transmitting the rotational force from the rotary drive shaft to the magnetic disc is arranged so that, when the rotary drive shaft is rotated, the center core receive member can be moved downward axially thereof using the rotational force of the rotary drive shaft to thereby bring the center core into positive engagement with the rotary drive shaft.
