I think they use capacitors that will hold enough charge to allow flushing the buffers to disk when there's a power loss.
And another set of caps to keep the spindles spinning so that data can be written? I'm not yet willing to buy the bridge you're selling. :)
10 or so years ago when the drives had significantly more rotating mass and significantly lower data density there were (high-end SCSI) drives that could use their rotational energy to power their electronics to write the data and adjust the dataclock as the spindle slowed, but I don't think any drive does this anymore.
