Actually, voice coil type heads park with no power at all. With no current the spring takes the heads to the park position automatically. What you say was true for stepper motor type heads, which have been out of use in PCs for... perhaps 20 years.

Even the cheapest of the cheap powersupplies can handle spikes of the duration

is available to handle spikes.
