MAGNETIC DISK DEVICE

PURPOSE:To obtain a disk device with high closeness by interposing an elastic packing material such as rubber between the edge of a dust preventing cover consisting of a thin plate material molded like a shape folding its edge to the outside by 180 deg. and a fitting base over all the periphery. CONSTITUTION:A magnetic disk 1 is supported by a spindle mechanism 2 so as to be rotated and a magnetic head 3 is supported by a head positioning mechanism 4 so as to be positioned on respective recording tracks. Both the mechanism 2, 4 are fixed on the fitting base 5 and the dust preventing cover 7 constituting a closed container 6 together with the base 5 is curled at its edge like a J-shaped cross section. A packing 8 is stuck to the dust preventing cover fitting face of the base 5 with sealing adhesives 9, a groove embedding block 11 is engaged with the curl part 10 of the cover 7 and the cover 7 is clumped on the base 5 with a screw 14 through a cushioning material 12 by hooking cover fittings 13 and the cover 7 is fixed while smashing the packing 8.
