Abstract:
A method, apparatus and program storage device for dynamically adjusting the write current in each head to compensate for variation in disk drive and environmental parameters is disclosed. A current in the write head is dynamically adjusted to compensate for variations in the components and environment by periodically measuring the writability of the drive and adjusting the write current such that the parameter stays within predetermined criteria.
