Each disk is placed in a special aerodynamic arc, forming the necessary air flow. The frame, at the ends of which the heads are placed, is locked off in a special parking zone outside the surface of the discs using a latch and (or) a magnet. After spinning up the spindle, airflow is created, the VCM board unlocks the frame and puts it into working position. The heads do not touch the surface of the discs, but fly over them on an air cushion. By the way, when the power is turned off, the rotation energy is enough to generate enough current to bring the heads to the parking zone (20-30 years ago it was necessary to run a high-level parking program)., , «» . , . - (). .
