ABSTRACT:
A magnetic disk drive unit or machine adapted to receive disk-jacket assemblies for magnetically reading from and writing on a disk in such an assembly. The jacket of the assembly is made of a material with high electrical resistance which accumulates static electricity through usual handling. The machine includes a skirt having an electrically conducting layer thereon and hung on an upper portion of the machine so that the skirt is in contact with an outer surface of the jacket for draining off an electrostatic charge accumulation on the jacket very quickly.
