Method and apparatus for driving VCM unloading HDD head

摘要

Provided are a voice coil motor (VCM) driving method for an HDD, related head unloading apparatus and recording media suitable for implementing the driving method. The method of driving a VCM to park a head on a ramp in the HDD includes; driving the VCM using a first driving voltage until the head moves to a first position; and thereafter driving the VCM using a second driving voltage higher than the first driving voltage during a first time period sufficient cause the head to rise along a first incline of the ramp.
