ABSTRACT:
A portable information processing apparatus in provided with a magnetic disk device switchable to a state providing increased resistance to physical shock upon prediction that such a shock is likely. Under predetermined conditions, a second prediction may be issued that such a shock is no longer likely, allowing the magnetic disk device to switch to a normal state of operations. The shock-resistant state of the magnetic disk device can prevent data access and thus inhibit the progress of important process(es). Upon recognition that an important process is being delayed, the condition for issuing the second prediction may be relaxed to more quickly return the magnetic disk device to a normal operating state.
