Abstract

The present invention provides a thinner-type magnetic disc apparatus while maintaining the stiffness of the case. The magnetic disc apparatus includes a magnetic disk 100, a spindle motor 109 that rotationally actuates the magnetic disk, a magnetic head 110 that records and reproduces information on the magnetic disk, a carriage 209 with the magnetic head mounted at its tip, a voice coil motor (VCM) 101 that drives the carriage, electronic components 200 and 201 for processing signals from the magnetic head and a case 102 that encloses these structural element. Electrical wiring 108 interconnects the magnetic head and the electronic components or interconnects the electronic components, or both, and is plated onto the inner bottom surface of the case. An interface connecting part 300 is plated onto the outer bottom surface of the case and is connected to electrical wiring that is plated onto the inner bottom and side-wall surfaces of the case. The case 102 is formed as a single unit from a resinous or metal material.
