The movable portion of the access mechanism in a disk drive must be electrically connected to the remainder of the system. This requires a number of conductors, the associated strain reliefs, clamps, guides, etc. The connection system shown in the drawing utilizes a flexible cable 1 which has a plug 2 for attachment to the fixed portion of the drive and a clamp 3 for the end of the cable which is affixed to the carriage 4. The clamp 3 is held in position on the carriage 4 by means of a screw 5. A spring 6 is used to provide a positive connection between the ground pad 1A on cable 1 and the carriage 4 through screw 5, as shown in the sectional view. A guide surface for cable 1 is provided by the guide 7. Fig. 2 shows how the cable 1 follows this surface as the carriage is moved in and out.
