Light gauge single strand hook-up wire would do, similar to the original wiring. Heavier gauge wiring might rip the small solder pads from the circuit board.

The power wires are securely soldered to the board okay. It's the five wires that connect the read/write head that have the problem. I have reconnected them but I am not convinced the connections are secure since every time I remove that "guitar" PC board one or more of these wires breaks off the board.

I think your idea of using single strand hook-up wire is a good one, ribbon cable will be too heavy, plus it's got to fit into a tight space. The real trick is stripping the insulation without breaking the wire.
