摘要：
A sealing type magnetic disc drive comprising a disc, a spindle motor for rotationally driving the disc, a head for recording or reproducing information on the disc, a base on which an actuator assembly is provided to move the head in the radius direction on the disc, and a cover jointed with the base, and low density gas is filled in the space where the base and the cover are joined, wherein low vapor pressure oil or a low viscosity adhesive is filled in a hole present at the joint of the base and the cover.
