But it gets more complicated in that the read and write energy must also be adjusted. It may not be impossible but it does get very complicated. Slamming the heads into the park position stop is much easier way to use the spin energy.
Simply maintaining energy to the cache memory is also much easier. But if the drive has lost power what happens to the computer running off the same power supply? It seems to me its cache will also be lost.
