A spindle motor assembly and an HDD(Hard Disk Drive) employing the assembly are provided to adopt a CSS(Contact Start Stop) method, and to comprise a vibration limiting unit for limiting vibration of a suspension to a predetermined range, thereby preventing a read/write head attached to the suspension from being physically damaged while improving impact resistance. An information storage disk(150) records or reproduces predetermined data by a read/write head(138), and is equipped with an area(P) where the head(138) is parked. A spindle motor(160) rotatively drives the disk(150), and has a hub into which the disk(150) is inserted. A clamp member(120) fixes the disk(150) to the hub by being pressurized on and contacted with the disk(150). A vibration limiting unit(125) disposed in a ring-shaped rim type is formed on an outer edge of the clamp member(120) so as to vertically face the parking area(P) at a spare interval.
