Claim:
1. A portable computing device, comprising: a magnetic disk unit of a portable computing device; a shock prediction module that predicts an occurrence of an impact to the portable computing device; a magnetic disk unit protecting module that carries out a magnetic disk unit protecting function that retracts a head of the magnetic disk unit in response to the shock prediction module predicting the occurrence of an impact; and a detecting module that detects whether a user is holding the portable computing device or not; wherein the magnetic disk unit protecting module, in response to the detecting module detecting that the user is holding the portable computing device while the shock prediction module predicts the occurrence of an impact and after the magnetic disk unit protecting module initializes the magnetic disk unit protecting function and the head of the magnetic disk unit begins to retract, temporarily deactivates the magnetic disk unit protecting function for a prescribed period, cancels the retraction of the head of the magnetic disk unit, and after a lapse of the prescribed period, activates the magnetic disk unit protecting function.
