Direct detection of coil resistance

   
   

Methods and computer program products for determining accurate estimates of coil resistance are provided. A voice coil voltage value and a corresponding voice coil current value are determined during a seek operation. Additionally, a velocity of the voice coil is determined based on servo information read from servo wedges of a disk during the seek operation. Coil resistance is estimated based on the voice coil voltage, the voice coil current and the velocity values.
