Enhanced Write Inhibit using Aboart History

      Disclosed is a method for write abort of a hard disk drive
using read/write head which has the offset between read and write
head element such as Magnet Resistive head.

      The merit of this method is using abort history which judges
whether the current servo positioning transient is critical or not.
Conventional method is just comparing criteria and only current servo
sector state which does not include the past transient related
information.  And it gives more reliability to the HDD products.

      The drive has an abort state history of each servo sector even
not in write operation.  The flow chart of this method is shown in
the
Figure.

      This method is not limited only in write operation head, but
read operation in any read/write head.
