ABSTRACT:
An apparatus for and a method of dummy writing in a data storage system. A dummy write is executed before executing a write mode and a write head pole tip is thermally fully expanded to reduce bit error rate occurring in the early writing. The dummy write is executed in inter sector gaps before the write mode is executed in the data storage system to thermally expand the head pole tip until the head pole tip is saturated. A level of a signal written in a sector in an initial write mode is lowered to prevent errors from occurring.
