So, what drives actually need to be 'parked'?
My understanding was that if
you de-energize the spindle motor and the voice coil that positions the
heads and the same time, the heads will have plenty of time to retract and
lock before the platters slow down enough for the heads to land. Was it
only needed on drives that used stepper motors for head positioning?
Either way, in what technology generation and/or time frame did the
requirement go away?
Drives NEED to be parked into a "safe landing" area. But newer drives
(e.g.: anything voice-coil based) park automatically the heads when the
voice coils are de-energized. Older drivers (with stepper motor used for
head positioning) needs to be parked. IIRC, it was in the innermost area of
the disk.
