1 and 2 are views showing an embodiment of the present invention.
FIG. 1 is a schematic diagram of the apparatus, and FIG. 2 is a conceptual diagram of internal wiring. In this embodiment, as shown in both figures, a magnetic disk (recording medium)
1, a magnetic head 2 for recording / reproducing information on / from the magnetic disk 1, a support arm 3 for supporting the magnetic head 2 via a support spring, and a head actuator for positioning the magnetic head 2 (positioning). Mechanism) 4 and a common bus 7 for power supply, signal, etc. in a housing 5 to form a unit 8, and a common bus 7 for power supply, signal, data, etc. is connected to a plurality of outer surfaces of the housing 5. Connector (connection mechanism) 9
Is provided.

The plurality of connectors 9 for connecting the common bus are connected as shown in FIG. 2 so that the same function can be obtained regardless of which connector is used.
