Abstract
PURPOSE:To prevent invasion of external noise into the titled device by using a metallic cover case so as to cover a part or all bonded parts of a chamber and a base plate of a magnetic disk device. CONSTITUTION:The metallic cover case 15 covering a part or all of the bonded part of the chamber 11 and the base plate 12 is provided. As a material of the cover case 15, a metal such as copper, aluminum, iron and their alloy is used but an existing material such as inexpensive aluminum alloy or iron alloy (copper) obtained easily is used as the material of the cover case 15. Thus, an electromagnetic noise made incident from a gap is shield with a low cost and the magnetic disk device immune to the external noise is obtained.
