ABSTRACT:
A magnetic disc mounting mechanism for use in a disc drive unit adapted to drive a magnetic disc while magnetically attracting and holding the disc on a spindle shaft. The coupling mechanism includes a forcible pressing member for forcibly fitting a center core of the disc onto the spindle shaft and a member which is adapted to release the pressing of the forcible pressing member while operating an ejecting mechanism. This member operates to release, after the forcible pressing member has pressed the center core of the disc onto the spindle shaft such as to couple the disc to the spindle shaft, the pressing force exerted by the pressing member so that the load of the spindle motor during driving the disc is reduced advantageously.
