<p>A method of switching heads in a hard disk drive having disks with information written using an offline STW method is provided. In the method, first, deviations between a reference head and each of the heads are calculated. A mapping table having the deviations between the reference head and each of the heads is written and stored in a memory. When a head switching operation is requested, a current head is switched to a new head to access a track whose number is the same as the track assessed by the current head. A deviation of a track on which the head is positioned, which is recorded in the mapping table, is applied to the virtual track address of the track on which the head is positioned, thereby obtaining the physical track address of the track on which the head is positioned. The requested track is accessed based on the obtained physical track address. <IMAGE></p> |
